The Lost Ambassador by E. Phillips Oppenheim

I smoked two pipes, one after the other, in a vain attempt to draw out some definite sequence of facts from the tangled web of happenings into which I seemed to have strayed. I came to the conclusion that Fate, which had bestowed on me a physique of more than ordinary size, a sound constitution, and muscles which had filled my study with various kinds of trophies, had not been equally generous in her dispensation of brains. Try as I would, I could make nothing of the situation in which I found myself. The most reasonable thing seemed to be to conclude that Louis was one of a gang of thieves, that I was about to become their accomplice, and that Felicia was simply the Delilah with whom these people had summoned me to their aid. Such a conclusion, however, was not flattering, nor did it please me in any way. Directly I allowed myself to think of Felicia, I believed in her. There were none of the arts of the adventuress about her methods, her glances, or her words.

She did not, for instance, in the least resemble the young lady with the turquoises, who had also been good enough to take an interest in me! I gave the whole thing up at last. Perhaps by the morrow I should know more, -- if, indeed, I thought, a little grimly, I knew anything! I could not help feeling that this little enterprise to which I had committed myself might turn out to be a serious affair. Even Louis had not tried to minimize the risks. I felt, however, that if it led me to any better understanding of the situation, I could welcome whatever danger it involved.
