“No. 847. Yours 63952 of yesterday's date. Begins. Hussein Effendi a prosperous merchant of this city left for Italy to place his daughter in convent Marie Theressa, Florence Hussein being Christian. He goes on to Paris. Apply Ralli Theokritis et Cie., Rue de l'Opera. Ends.”
Half an hour later T. X. had a telephone connection through to Paris and was instructing the British police agent in that city. He received a further telephone report from Paris the next morning and one which gave him infinite satisfaction. Very slowly but surely he was gathering together the pieces of this baffling mystery and was fitting them together. Hussein Effendi would probably supply the last missing segments.
At eight o'clock that night the door opened and the man who represented T. X. in Paris came in carrying a travelling ulster on his arm. T. X. gave him a nod and then, as the newcomer stood with the door open, obviously waiting for somebody to follow him, he said,
“Show him in—I will see him alone.”
There walked into his office, a tall man wearing a frock coat and a red fez. He was a man from fifty-five to sixty, powerfully built, with a grave dark face and a thin fringe of white beard. He salaamed as he entered.
“You speak French, I believe,” said T. X. presently.
The other bowed.
“My agent has explained to you,” said T. X. in French, “that I desire some information for the purpose of clearing up a crime which has been committed in this country. I have given you my assurance, if that assurance was necessary, that you would come to no harm as a result of anything you might tell me.”
“That I understand, Effendi,” said the tall Turk; “the Americans and the English have always been good friends of mine and I have been frequently in London. Therefore, I shall be very pleased to be of any help to you.”
T. X. walked to a closed bookcase on one side of the room, unlocked it, took out an object wrapped in white tissue paper. He laid this on the table, the Turk watching the proceedings with an impassive face. Very slowly the Commissioner unrolled the little bundle and revealed at last a long, slim knife, rusted and stained, with a hilt, which in its untarnished days had evidently been of chased silver. He lifted the dagger from the table and handed it to the Turk.
