It was cunning, as well as clever, no doubt: but then, I told myself, it was the business of a person in Monsieur Girard's profession to be cunning.
I introduced myself as Mr.Sanford, the name I had been told to give at the Elysee Palace Hotel.

This seemed best, as it was in the hotel that I had been recommended to Monsieur Girard, and complications might arise if George Sandford suddenly turned into Ivor Dundas.

Besides, as there were a good many things which I did not want brought to light, Sandford seemed the man to fit the situation.

Later, he could easily disappear and leave no trace.
I said that I had been robbed of a thing which was of immense value to me, but as it was the gift of a lady whose name must not on any account appear in the case, I did not wish to consult the police.

All I asked of Monsieur Girard's well-known ability was the discovery of the supposed thief, whom I thereupon described.
