he Big Boy Next Door.Bets was feeling very excited. Her big brother Pip was coming home from schoolthat day for the long summer holidays. She had been without him for threemonths, and had felt very lonely. Now she would have him again."And Larry and Daisy will be home tomorrow!" she said to her mother. "Oh,Mummy! it will be fun to have so many children to play with again."Larry and Daisy were Pip's friends. They were older than Bets, but they lether play with them. In the Easter holidays the four of them, with another boyand his dog, had had a great adventure finding out who had burnt down acottage."We were the Five Find-Outers," said Bets, remembering everything. "We foundout the whole mystery, Mummy, didn't we? Oh, I do wish we could solve anothermystery these holidays too!"Her mother laughed. "Oh, it was just a bit of luck that you solved the mysteryof the burnt cottage," she said. "There won't be any more mysteries, so don'texpect any, Bets. Now hurry up and get ready. It's time to meet Pip."Pip was most excited to be home again. When he got back with Bets he toreround the garden, looking at everything. It seemed to him as if he had beenaway for years.His little sister tore round with him, chattering at the top of her voice allthe time. She adored Pip, but he didn't take very much notice of her. To himshe was only just a little girl, still a baby, who liked her dolls, and criedwhen she fell down."Larry and Daisy are coming back tomorrow," she panted, as she rushed roundafter Pip. "Oh, Pip! do you think we can be the Find-Outers again?""Only if there is something to find out, silly," said Pip. "Oh! I forgot totell you, Fatty is coming for the holidays too. His parents liked Peterswoodso much when they stayed here at Easter, that they have bought a little house,and Fatty will be here for the hols.""Oh, good!" said Bets happily. "I like Fatty. He's kind to me. We shall reallybe the Five Find-Outers again then; and oh, Pip! I suppose Buster is coming,isn't he?""Of course," said Pip. Buster was Fatty's little black Scottie dog, loved byall the children. "It will be nice to see old Buster again.""How do you know about Fatty coming?" asked Bets, still trotting round afterPip."He wrote to me," said Pip. "Wait a minute — I've got the letter here. He senta message to you in it."The boy felt in his pockets and took out a crumpled letter. Bets took it fromhim eagerly. It was very short, written in extremely neat handwriting."DEAR PIP, — Just to say my parents have bought White House, not far from you,so I'll be seeing you in the summer hols. Hope we have another mystery tosolve. It would be fun to be the Five Find-Outers and Dog again. Give my love
