I knew the firm for which this man worked. Having taken the printed description. I eliminated everything from it which could be the result of a disguise--the whiskers, the glasses, the voice, and I sent it to the firm, with a request that they would inform me whether it answered to the description of any of their travellers. I had already noticed the peculiarities of the typewriter, and I wrote to the man himself at his business address asking him if he would come here. As I expected, his reply was typewritten and revealed the same trivial but characteristic defects. The same post brought me a letter from Westhouse & Marbank, of Fenchurch Street, to say that the description tallied in every respect with that of their employé, James Windibank. Voilà tout!"

"If I tell her she will not believe me. You may remember the old Persian saying, 'There is danger for him who taketh the tiger cub, and danger also for whoso snatches a delusion from a woman.' There is as much sense in Hafiz as in Horace, and as much knowledge of the world."
