find that apparently he was well contented with what had happened
in the case so far.

"I shall be busy for a few hours in the laboratory, Walter," he
remarked, as we parted at the subway. "I think, if you have
nothing better to do, that you might employ the time in looking up
some of the gossip about Mrs. Maitland and Masterson, to say
nothing of Dr. Ross," he emphasised. "Drop in after dinner."

There was not much that I could find. Of Mrs. Maitland there was
practically nothing that I already did not know from having seen
her name in the papers. She was a leader in a certain set which
was devoting its activities to various social and moral
propaganda. Masterson's early escapades were notorious even in the
younger smart set in which he had moved, but his years abroad had
mellowed the recollection of them. He had not distinguished
himself in any way since his return to set gossip afloat, nor had
any tales of his doings abroad filtered through to New York
clubland. Dr. Ross, I found to my surprise, was rather better
known than I had supposed, both as a specialist and as a man about
town. He seemed to have risen rapidly in his profession as
physician to the ills of society's nerves.

I was amazed after dinner to find Kennedy doing nothing at all.

"What's the matter?" I asked. "Have you struck a snag?"

"No," he replied slowly, "I was only waiting. I told them to be
here between half-past eight and nine."
