The man spoke in a low tone, and its timbre and inflection betrayed what is called the voice of a gentleman, he said.
"You have been brought here," the man said, "to give certain information, and to reveal certain secrets. If you do this, you will be released at onceyou will be taken away from here in an unconscious state, just as you were brought here, and set down in the night not far from your hotel. If you refuse, you will be taken out during the night, and dropped into the Thames."
The man had then gone on to question him. The questions he had asked had been numerous, and one and all had had to do with persons of high station with whom Jack was on terms of intimacyall of them rich people. What most astonished him, he said, was that his unseen interlocutor should know so much about himhis questions and remarks showed how much he knewand that he should apparently know who all his friends were.
Jack could not remember all the questions he had been asked, but he repeated some of them. Whereabouts did the Duchesse de Montparnasse keep her jewels in her château on the Meuse? The questioner said he knew that Osborne could tell him, because he knew that Osborne, just before going to Nigeria, had, while staying at that château, been shown by the Duchesse herself her priceless jewelleryone of the finest collections in the world, chiefly valuable owing to its interesting historic associations.
Then, in which apartment in Eldon Hall, in Northumberland, the seat of the Earl of Cranmere, was the large safe that Lord Cranmere had bought ten months before from an American firm, the name of which was given? He said that he, Osborne, must know, because he was a guest at Lord Cranmere's when the safe arrivedwhich was the truth. He also wanted to know if there were a priests' hiding-hole in Eldon Hall, as was the case in so many of the large country mansions built about the same period, and, if so, its exact whereabouts in the house.
As Jack Osborne said this, my thoughts flashed away to Berkshire, to Holt Manor, to the dark, depressing hiding-hole there that I had peered down into more than once. Who had spoken to me of that hiding-hole only recently? Why, Dulcie, of course. She had mentioned it whilst telling me about Mrs. Stapleton, and about Sir Roland's showing the young widow over the house. Dulcie had mentioned it specially, because Mrs. Stapleton had evinced such evident interest in it.
I checked my train of thought, focussing my mind upon that single incident.
Mrs. Stapleton, the "mysterious widow" of whom nobody appeared to know anything, had been strangely interested in that hiding-hole and in all that Sir Roland had said about itDulcie had told me that. The hiding-hole was in close proximity to Sir Roland's bedroom, and to one other room from which valuable jewellery had been stolen. Mrs. Stapleton had left the neighbourhood on the day after the robbery, had been absent ever sincethat of course might be, and probably was, merely a coincidence. At supper at Gastrell's reception in Cumberland Place Mrs. Stapleton had acknowledged "Mrs. Gastrell's" smile of recognition, and an instant later the two women had stared at each other stonily, and Mrs. Stapleton had assured me that she did not know the other woman, that she had "never seen her before." Then those two men, of whom Osborne had just spoken, had of their own accord joined him and "Mrs. Gastrell" at supper, and eventually he had gone with the men to their flat in Bloomsbury. And now here was an unseen man, evidently a scoundrel, inquiring the whereabouts of a safe in a country house belonging to a nobleman known to be extremely rich, and asking in particular if the house possessed a priests' hiding-hole, and if so, exactly where it was locateda man who threatened evil if the information were withheld. Could all this, I could not help wondering, be mere coincidence? Then on the top of it came that extraordinary telegram sent to Dulcie from London, with my name attached to it.
Jack, however, had not done relating his adventures, so I turned again to listen to him.
"A third thing the fellow asked," he said, "was the name of Hugo Salmonsteiner's bankersSalmonsteiner the millionaire timber-merchant whose son was out big-game shooting with me a year ago. It seemed an absurd question, for surely it must be easy to find out who any man's bankers are, but still he asked me, and appeared to be most anxious that I should tell him. Oh, but there were scores of other questions, all much on the same lines, and tending to extract from me information of a peculiar kind."
