I refrained from going to Scotland Yard, as I thought Voltaire would be watching me.

I gave this detective a description of Voltaire, told him his address, which I had ascertained through his letters to Temple Hall, and explained my wishes to him.

He took up my points very quickly, saw what I wanted without any lengthened explanations, and expressed a willingness to serve me.

So much pleased was I with this interview, that I had no fear that my enemy would not be well looked after.
After that I took train for Dover, and prepared to track Kaffar, if possible, wherever he had gone, not realizing at the time the task I had proposed for myself.
I thought I made a forward step at Dover, for, on inquiring at an hotel there, I found that a man answering to Kaffar's description had engaged a bedroom for one night, and had gone on to Calais by the midday boat, in time to catch the express for Paris.
"Did this gentleman have any luggage ?" I asked.
The hotel proprietor did not think the gentleman carried any luggage, but he would inquire.
On inquiry of the hotel porter, I found that he carried a Gladstone bag, rather small and new.

This was particularly remembered--first, because the foreign gentleman seemed very particular about it, and, second, because there seemed to be nothing in it.
So far so good.
I determined to go on to Paris; it could do no harm, it might do good.
