Of course he might have means of keeping him there in strict secrecy, or he might have a score of disguises to keep him from detection.

Still I thought the balance would be heaviest on the side of his returning to Egypt.

I naturally thought he would return to his native land, because I had heard him say he talked none of the European languages besides English and a smattering of Turkish.
My next step, therefore, was to return to London, and then go to Dover, Calais, Newhaven, and Dieppe, to try to see whether Kaffar could be traced.

At the same time, I determined to have a watch set upon Voltaire, and his every step dogged, so that, if he held any communication with Kaffar, necessary steps might be taken to prove to Miss Forrest my innocence, and thus she might at once be freed from the designs of the man she hated.
No sooner did I arrive in London, however, and took possession of my easy-chair than I knew Voltaire wanted me to go to him, and I knew, too, that a month before I should have had to yield to the power he possessed.

I need not say that I did not go.
