One man there was who might have helped the search, Earl Dexter. But Earl Dexter was himself wanted by Scotland Yard!
From the time of the bank affair up to the moment when this beautiful visitor had come to my chambers I had thought Dexter, as well as Hassan, to have fled secretly from England. But the moment that I saw Carneta at my door I divined that The Stetson Man must still be in London.
She sat watching me and awaiting my answer.
“I cannot avenge my friend unless I can find his murderer.”
Eagerly she bent forward.
“But if I can find him?”
That made me think, and I hesitated before speaking again.
“Say what you came to say,” I replied slowly. “You must know that I distrust you. Indeed, my plain duty is to detain you. But I will listen to anything you may care to tell me, particularly if it enables me to trap Hassan of Aleppo.”
“Very well,” she said, and rested her elbows upon the table before her. “I have come to you in desperation. I can help you to find the man who murdered Professor Deeping, but in return I want you to help me!”
I watched her closely. She was very plainly, almost poorly, dressed. Her face was pale and there were dark marks around her eyes. This but served to render their strange beauty more startling; yet I could see that my visitor was in real trouble. The situation was an odd one.
