Trevor had been staring at the ruins for some time, when he looked up
to see Clowes standing in the doorway.

"Hullo," said Clowes, "been tidying up?"

Trevor made a few hasty comments on the situation. Clowes listened
approvingly.

"Don't you think," he went on, eyeing the study with a critical air,
"that you've got too many things on the floor, and too few anywhere
else? And I should move some of those books on to the shelf, if I were
you."

Trevor breathed very hard.

"I should like to find the chap who did this," he said softly.

Clowes advanced into the room and proceeded to pick up various
misplaced articles of furniture in a helpful way.

"I thought so," he said presently, "come and look here."

white card, and on it were the words, _"With the Compliments of the

"What are you going to do about this?" asked Clowes. "Come into my room
and talk it over."
