“Maybe it would be better to knock on her door,” said Violet. “What would happen then?”

  “She wouldn’t come to the door. You can be sure of that. At least she never has. A few people tried it long ago. They wanted to be friendly, but she never came to the door. So nobody goes now.”

  “There’s always a first time,” Benny said. “I’d rather talk to her at her own house than in a store anyway.”

  “Well, if you have something you really want to talk to her about,” said the clerk, “I suppose you can try. No harm done, unless you get your feelings hurt. I’d like to see you try, I really would.”

  Benny was thinking to himself that the clerk must wonder why the Aldens wanted to see Mary Smith. But he was not going to say anything to explain.

  “I think we will try to see her,” said Jessie. “We really want to. Thank you for your help.”

  As the Aldens went down the street, Benny said, “He did help us, and he never asked us why we wanted to talk to Miss Smith.”

  “But he was dying to know,” Henry agreed. “And I don’t blame him. Let’s walk over and knock at that door at the side of the Tower House.”

  As the Aldens came nearer, they could see that the house did indeed look empty except for the first floor of one of the back towers. There were curtains in the windows and at the door. They looked thick and were a dark color.

  “I’m just as glad we are coming in the daylight,” Violet said. “There is something spooky about this old house.”

  Henry said, “Do you have the locket, Benny?”

  “It’s in my pocket, wrapped in a paper,” Benny said. “I don’t want to show it until Miss Smith describes it.”

  Jessie looked at the house and said almost in a whisper, “I have a feeling we are being watched. Don’t you feel that way, too?”

  “There are four of us and just one Miss Smith,” Benny said. “There’s nothing to worry about.” But just the same Benny said, “Henry, you rap at the door.”

  Henry knocked. Nothing happened.

  “Just what the man said would happen,” Benny said. “Try again, Henry.”

  Henry tried a fancy rap: Da-da-da-Dum-da.

  The Aldens waited. Then to their surprise the door slowly opened and a woman looked at the visitors.

  What a cold, grim face, without a sign of a smile!

  Benny thought, “She’d be nice looking if she was even the least bit friendly.” Her face was round and very fair. Her hair was light brown and curly, but pulled straight back into a tight knot. She did not even ask, “What do you want?”

  Henry spoke for all the Aldens. “You are Miss Smith?” he asked. “Miss Mary Smith?”

  The woman nodded.

  “We found something down on the beach,” Henry went on. “It was buried in the sand. We think it has something to do with this house.”

  Benny’s hand closed around the locket in the paper, but he left it in his pocket.

  The woman looked quickly and sharply from one of the visitors to the next. Then she said, “I haven’t lost anything. Please don’t bother me.”

  She shut the door, and the Aldens heard the key turn in the lock.

  “Well, that is too bad,” said Violet, really feeling hurt. “I’m sorry for anyone like that. She must be very unhappy.”

  Benny was thinking fast. As they walked away from the Tower House he said, “Two things. First, the initials on the locket are R.L. That doesn’t fit with Mary Smith. And second, did you notice that smell when the door was opened? What was it?”

  Henry wrinkled his nose. “You are right, Benny,” he said. “There was a strong smell—for a minute I thought of a zoo, or a circus. What could it be?”

  “Maybe we’ll never know,” said Violet.

  “Oh, yes, we will, Violet,” Benny said quickly. “You just wait. Have we ever given up on a mystery? And this one is the easiest of all. You’ll see.”

  Henry looked at Benny and laughed. “All right, what do you plan to do next, Benny?”

  “How about lunch?” Benny asked. “I saw two or three places on Main Street where they serve meals. I want a piece of apple pie. My head works better when my stomach is full.”

  Jessie looked back at the Tower House. Nothing was changed. No one was watching from a dark window. But Jessie felt uneasy just the same.

  CHAPTER 5

  A Hundred Cats!

  The Aldens found a small restaurant on Main Street. There was a large sign with an apple painted on it.

  “The Red Apple,” Benny said. “This place ought to have apple pie, don’t you think?”

  The Aldens went in, and the girl showed them to a table for four.

  Jessie said, “Let’s have something I can’t cook in the trailer kitchen.”

  “Roast lamb and baked potato for me,” Henry said. “You could never roast lamb in our oven. And I am hungry after all the excitement of last night and this day.”

  They all agreed on lamb—all but Benny. “No,” he said, “I’ll stick to my hamburgers and peanut butter sandwiches.”

  “Benny,” objected Jessie, “why have the same old thing? You can have a change.”

  “I don’t like a change,” answered Benny. “I like peanut butter, and for dessert, apple pie and cheese.”

  “Well, sandwiches are cheaper,” said Henry.

  The food was delicious, and the waitress pleasant. She laughed at Benny with his peanut butter. She said, “I’ve got a young brother like you. He never gets tired of peanut butter and jelly.”

  “Oh, I forgot the jelly,” Benny replied. “I’d like that, too.”

  As the Aldens were eating, the manager came up to their table and asked if everything was all right.

  “Oh, yes,” replied Jessie. She noticed that the manager was an older man and that gave her an idea. “We are curious about that Tower House,” she said. “It is so different from anything else in town. Do you know who lives there and who owns it?”

  “Well,” answered the manager, “I don’t remember the Lane family myself, but I think the house is still owned by the Lanes. But then I may be wrong. I think all the Lanes are dead. Miss Mary Smith lives there all alone.”

  At the mention of the name Lane, Benny looked up quickly. Could the L on the locket stand for Lane? That surely seemed a good guess.

  “Do you remember when Miss Smith moved in?” asked Henry.

  “Well, yes and no, you might say,” the manager answered.

  “I guess you mean you were too young to remember,” said Benny.

  The man laughed. “No, I am not too young. I was right here when suddenly, just like that, Miss Mary Smith lived in the Tower House. She came in the night and nobody saw her move in. When morning came, bang! there she was.”

  “You see her around Beachwood?” Jessie asked.

  “She comes out once in a while to buy food or to go to the post office. That’s about all. I’d say she just doesn’t like people.”

  “That’s funny,” said Benny. “I can’t understand that.”

  The manager smiled at Benny and said, “Well, you like everybody. That’s why you can’t understand.”

  But Benny did not quite agree. He said, “I think everyone likes people. But some people don’t know that they do.”

  “Maybe you are right,” the older man said. “I have an aunt who never smiles, but it is because she is shy.”

  “We have a special reason for wanting to talk to Miss Smith,” Henry told the manager. And he explained about the locket with the picture of the Tower House in it.

  “And the L must stand for Lane,” Benny added. “You have already helped us.”

  “I’m surprised Miss Smith even opened the door,” the man said. “She is a strange person. Now, understand—I don’t know this for a fact—but I think Miss Smith is an artist and paints pictures.”

  Benny looked surprised. “Why?” he asked. “Why do you think so?”

  “About every month or so, I know that Miss Smith mails a package t
o New York. I understand it always goes to the same address, which is on one of the avenues where dealers buy and sell paintings. Pictures come through in a special kind of box. I used to work in a city post office, and that’s how I know. Miss Smith uses the same kind of box.”

  “Miss Smith may be a painter,” Violet said thoughtfully.

  “I don’t know what she paints,” the man said. “She hardly ever goes out. She doesn’t look around her or paint the sea or houses.”

  Violet said, “A real artist can paint anything and sell it. A door or a window or an old chair.”

  Benny said, “Even a design in a carpet.”

  The man laughed. “I suppose you’re right. Anyway if she is an artist, that is probably the way she earns money.”

  “Wouldn’t you think she would want people to see her work?” asked Violet. “She sounds so odd.”

  The manager went on slowly and his voice was low. “I do hear all sorts of wild stories about Miss Smith. Of course I am not ready to believe them. But I have heard that she keeps a hundred cats in that tower.”

  “A hundred cats!” exclaimed Jessie. “I can’t believe that many, but maybe one or two.”

  “Or no cats at all,” added the manager. “People like to make up stories about anyone they don’t understand.”

  Benny said, “I bet she does keep cats. When she opened the door, we were standing near enough to smell something. It really smelled like the lion house at the zoo. What a smell!”

  The manager looked at Benny. “That is the first real proof I have ever heard that there might really be cats at the Tower House. People are often a lot like their pets. Miss Smith is like a cat, very quiet.”

  “What makes you say that?” asked Benny.

  “When she buys stamps and envelopes, she has a little paper she gives to the clerk, saying how many stamps she wants and what kind. Miss Smith doesn’t have to say a word. She pays for them and goes out. She always seems to have money.”

  “But I should think she would be interested in a locket that has a picture of her own house,” Benny said. He felt there was a puzzle here he should be able to solve. “Would you like to see the locket?”

  “Indeed I would,” said the man. He held the locket and then opened it carefully.

  “Well,” he said in surprise. “You didn’t tell me there was a picture of a cat inside. I am sure that this cat must have died long ago. But probably Miss Smith has a young cat a lot like this. Who knows?” He laughed.

  Benny put the locket back in his pocket.

  Henry said, “I guess we’ll have to think what to do next. You have helped us a lot. Now we have some idea of what Miss Smith does to keep busy.”

  Jessie said, “Let’s go back to the beach. We’ve done enough today.”

  On the way back to the trailer, Benny said, “I can’t wait to tell Mr. Lee what we have learned so far.”

  “I wonder if we’ll see anyone walking on the beach at midnight,” said Henry.

  Violet said, “I hope not!”

  Benny really meant to wake up during the night. He wanted to see if anyone would be on the beach at midnight. But he swam so much that he slept very soundly. Nothing as quiet as footsteps in the sand could waken him. Henry never stirred, and neither did Jessie or Violet.

  Early in the morning, however, the Aldens were outside, having breakfast as usual. The kettle was boiling, and Mr. Lee’s special chair and cup were ready.

  “He’s late,” Benny said.

  “Not yet,” replied Henry. “But we ought to see him in the distance.”

  Then he came, walking along with Richard and carrying his metal-finder. He did not stop often because he wanted to see the Aldens as much as they wanted to see him. He walked faster and was soon near enough to speak.

  “How did you get along in town?” he called.

  “Quite well,” said Jessie, pouring the hot tea.

  “You are spoiling me,” said the old gentleman. “When you go home, I shall miss my extra breakfast. Do tell me what you did.”

  One by one, the Aldens told about Miss Smith’s closing the door in their faces, about the Red Apple, the manager’s ideas, and the cats.

  Mr. Lee nodded. “The manager is right about the cat in the picture. It can’t be living now. But it was surely a beautiful cat.”

  “We’re going to see if we can find out more about Miss Smith,” Benny said. “I still wonder why she didn’t even want to see the locket.”

  “Mr. Lee, what did you do while we were gone?” asked Jessie.

  “Oh, I was going to tell you,” he said, fishing in his pocket. He took out a very large coin. “I found this buried two feet down, right in front of the biggest cottage. It is a very old coin and I should think valuable.”

  The Aldens looked at the old coin. “Think how long this has been lost!” exclaimed Jessie.

  “Yes,” said Mr. Lee. “It may have been lost way up under the cottage long before there was a house there. It probably worked its way downhill. I have marked the place. I shall dig deeper there this winter and may find other things. There is no one around to bother me when the weather is cold.”

  “Someone at the cottage didn’t lose that coin?” asked Violet.

  “No, I’m sure not. They have been here only a week, and the coin was buried deep. It was lost a long time ago. Once I found a 1937 buffalo nickel. That is a very special coin, too. And yesterday I found a Boy Scout pin. It belonged to the boy in the house next to mine. That was the best part of my day—to see his face when I gave him his pin.”

  The Aldens couldn’t help but notice that the best part of Mr. Lee’s adventure had been finding the Boy Scout pin, not the valuable coin.

  CHAPTER 6

  Benny to the Rescue

  After Mr. Lee had gone, Benny said, “I’ll tell you what let’s do. Let’s drive around behind the Tower House. If we go very slowly maybe we can see a back window. We wouldn’t seem to be looking.”

  “Fine,” said Henry. “I can’t believe those stories about a hundred cats are true.”

  “Maybe they are, Henry,” said Jessie. “Remember that strong smell.”

  “Let’s go,” said Benny. He took his tray into the kitchen, and the others followed.

  Soon the Aldens were driving up a beach road they had not taken before. It suddenly turned to the right.

  “I guess nobody uses this road,” said Henry. “We’ve met no cars or people.”

  “Slower!” said Benny. “Just crawl along, and then we can see.”

  But there was not much to see, even though Henry drove as slowly as he could. Large trees stood at the back and sides of the Tower House. Everything looked wild and as if no one cared.

  All at once the Aldens saw two small boys. They had towels around their shoulders. They were going to the beach. The boys noticed the Aldens looking toward the Tower House.

  “Hey!” called one of the boys. “Going to see the old witch?”

  Henry stopped the car. “Old witch?” he asked.

  “Yeah,” replied the boy, pointing to the Tower House. The upper floors of all the towers were boarded up. “Don’t you know an old witch lives there with one hundred cats?”

  Violet said in a quiet voice, “How do you know?”

  “Everybody knows. Ask anybody.”

  The other boy said, “I know I’d never go there. Not on a bet.”

  Jessie said, “We saw the woman who lives there. Her name is Miss Mary Smith.”

  “Aw, you saw her by daylight, going grocery shopping. You never saw her running on the beach at night, I bet. She goes to howl at the moon.”

  “Nonsense!” said Jessie. “Nobody howls at the moon, except maybe dogs.”

  “You’re sure of yourself, aren’t you? Well, we’re warning you. Don’t hang around this house. She can put a hex on you as easy as looking at you. And she’s got those hundred cats. Cats can be crazy, too. She feeds them raw meat.”

  “Doesn’t she buy cat food?” asked Violet.

/>   “Naw, never. She buys raw meat, pounds of it, and that makes them wild. Didn’t you ever hear of an old witch and her cats?”

  “Yes, on Halloween,” answered Henry. “But Miss Smith is a real person, not a witch.”

  “Have it your way,” said the other boy. “You’ll get out of here if you know what’s good for you. Just don’t have anything to do with the Tower House. It’s haunted.”

  “We don’t believe in haunted houses,” said Benny. “There is always some reason if you can just find it.”

  “That’s what you think. For one thing, her name can’t be Mary Smith. That’s just a made-up name. And why does she shut herself up and never speak to anybody?”

  The first boy said, “One day I threw a stone at that window, the big one. And you know what? Mary Smith got a big piece of glass and lugged it home and put it in herself. Never said a word about it to anybody.”

  “You think that was crazy?” asked Benny.

  “Yes, I do. Anybody else would have told the police. But she didn’t. You know why? She doesn’t want the police to know too much about her. She’d rather pay for that big window pane and fix it herself.”

  Henry asked, “Why did you break her window, anyway?”

  “Well, I just felt like throwing a stone, and the kid with me said to go ahead. He’d like to see what she would do about it.”

  “And you found out,” Benny nodded. “I’m sorry for Miss Smith or whoever she is. That glass must have cost plenty. It must have been heavy, too.”

  “The old witch has money, that’s for sure,” said the boy. “She buys lots of food for herself. I’m not sorry for her. You can be sorry if you like, not me.”

  And the two boys went off, swinging their towels.

  The Aldens sat perfectly still in the car. At last Jessie spoke slowly. “Of course Miss Smith isn’t a witch. But there is something very wrong about her. I wish I knew what it was.”

  “Yes,” agreed Benny. “I don’t know why she didn’t take the locket. She could have looked at it anyway. But she just shut her door.”

  The Aldens looked toward the big window behind the bushes. There was no curtain. Nothing moved inside. There was no sound.
