“Right you are,” said Parker, and took the receiver off its hook.

“And now,” said his friend, when the message was delivered, “just come into the library for a minute.”

On the library table, Lord Peter had spread out a series of bromide prints, some dry, some damp, and some but half-washed.

“These little ones are the originals of the photos we’ve been taking,” said Lord Peter, “and these big ones are enlargements all made to precisely the same scale. This one here is the footmark on the linoleum; we’ll put that by itself at present. Now these finger-prints can be divided into five lots. I’ve numbered ’em on the prints—see?—and made a list:
