"_Under_ the bed? What's the good of that? Did you go over every inch of the strip of carpet leading to the chair with a magnifying-glass?" "Hadn't got a magnifying-glass." "Then you'd better buck up and get one, if you're going to be a detective. Do you think Sherlock Holmes ever moved a step without his? Not much. Well, anyhow. Did you find any foot-prints or tobacco-ash?" "There was a jolly lot of dust about." "Did you preserve a sample?" "No." "My word, you've a lot to learn. Now, weighing the evidence, does anything strike you?" "No." "You're a bright sort of sleuth-hound, aren't you! It seems to me I'm doing all the work on this case. I'll have to give you another leg-up. Considering the time when the quid disappeared, I should say that somebody in the dormitory must have collared it. How many fellows are there in Evans' dormitory?" "I don't know." "Cut along and find out." The detective reluctantly trudged off once more. "Well?" said Scott, on his return. "Seven," said Pillingshot. "Counting Evans." "We needn't count Evans. If he's ass enough to steal his own quids, he deserves to lose them. Who are the other six?" "There's Trent. He's prefect." "The Napoleon of Crime. Watch his every move. Yes?" "Simms." "A dangerous man. Sinister to the core." "And Green, Berkeley, Hanson, and Daubeny." "Every one of them well known to the police. Why, the place is a perfect Thieves' Kitchen. Look here, we must act swiftly, young Pillingshot. This is a black business. We'll take them in alphabetical order. Run and fetch Berkeley." Berkeley, interrupted in a game of Halma, came unwillingly. "Now then, Pillingshot, put your questions," said Scott. "This is a black business, Berkeley. Young Evans has lost a sovereign----" "If you think I've taken his beastly quid----!" said Berkeley warmly. "Make a note that, on being questioned, the man Berkeley exhibited suspicious emotion. Go on. Jam it down." Pillingshot reluctantly entered the statement under Berkeley's indignant gaze. "Now then, carry on." "You know, it's all rot," protested Pillingshot. "I never said Berkeley had anything to do with it." "Never mind. Ask him what his movements were on the night of the--what was yesterday?--on the night of the sixteenth of July." Pillingshot put the question nervously. "I was in bed, of course, you silly ass." "Were you asleep?" inquired Scott. "Of course I was." "Then how do you know what you were doing? Pillingshot, make a note of the fact that the man Berkeley's statement was confused and contradictory. It's a clue. Work on it. Who's next? Daubeny. Berkeley, send Daubeny up here." "All right, Pillingshot, you wait," was Berkeley's exit speech. Daubeny, when examined, exhibited the same suspicious emotion that Berkeley had shown; and Hanson, Simms, and Green behaved in a precisely similar manner.
