"We'll have to try and find out where Miss Harmer was between four and five o'clock today," said Pip.
"Who else is there?" said Daisy. "We've got Miss Tremble, Lady Candling, and Miss Harmer down. What about the cook and house-parlourmaid next door? They would have had a chance of going down to the cat-house and taking Dark Queen, wouldn't they?"
"I've never seen the cook or parlourmaid," said Pip. "None of us have. We'll have to find out about them too. Goodness, we've got quite a lot of suspected people after all! We'll have a lot of work to do!"
"The one person who is horrid enough to have done it is Tupping — and he's just the very one we can't even suspect," said Bets sadly. "Well, there aren't any more Suspects, are there?"
"We'll have to put old Luke down," said Larry. "I know we don't suspect him — but Tupping has accused him of the crime, so we'd better put him down. We can cross him out as soon as we like."
So Luke's name went down too. Poor old Luke! He always seemed to be in trouble.
"Let's go and whistle to him," said Larry. "He hasn't gone home yet, or he'd have whistled to us and told us everything."
So they went to the wall and whistled the special notes that they and Luke used for signalling to one another. But although they whistled and whistled, nobody came. Whatever could Luke be doing?
Luke gets into Trouble
The five children sat on top of the wall, with Buster scratching at the bricks below. They wondered what to do. Pip looked at his watch.
