Goodall came up to the desk. “Is this the piece of note-paper, Clegg? Just where you found it?”

“Yes, Inspector!” Bathurst joined the Inspector. The message was there just as it had been written by the dead man. Bathurst let the Inspector read it—then extended his hand for it. “May I see it?”

Goodall passed it over. Anthony produced his magnifying glass and then covered all the writing with another sheet of paper—that is to say, from “urgent” to “M. L.” Then he carefully examined with his glass the part of the paper immediately following the letter “L.” Peter Daventry watched him curiously. After a moment or two he put down the sheet of paper and replaced his magnifying glass. Clegg’s eyelid flickered as he caught a glance from Goodall, but the latter gave no other sign of interest.

Suddenly he picked up the ink-bowl and held it up carefully to the light. He swirled the ink round and round in the bowl three or four times and watched its black eddy with the greatest keenness. Apparently what he saw gave him entire satisfaction—which his face showed when he replaced the ink-bowl on the desk. He rubbed the palms of his hands together. “You were quite right, Inspector, regarding your theory of the crime. I hope to put my hand on the——”
