"An attack in Singapore — a plot in Russia — an attempted murder in France — a man who told and died.
There was something else. I have it! Bernardo Chefano — the twisted lips — they will identify him no matter what disguise or alias he may use."
"Ah!" exclaimed Harry. "There's something! We can connect some one else with Isaac Coffran. Did the ape-man have twisted lips?"
"No," said Duncan, "he was hardly a man at all, as I remember. Of course the hashish had me pretty well doped that night. I might have seen anything. Bernardo Chefano. He can't be Pedro, either. Wait! Some one had charge of that strange creature that came into my room. Some one whistled outside. That might have been Pedro, of course. It couldn't have been old Coffran. So it may not have been this fellow Chefano after all."
He happened to see the paper that lay on the foot of the bed. He had forgotten it.
"Look," he said. "Abdul gave me this. It fell out of Coffran's pocket the night he was at my house. Some one sent it to him. That indicates the extra man!"

" 'Investigate personally.' " He did that. Came to the house; most unusual for him.
" 'Prevent all interference.' " That was Coffran's scheme all right. With you out of the way, there could be no interference — on your part at least, and the message deals with you.
" 'Plans are working perfectly.' "
