All had gone well until they had touched the handle of the safe door, which had set off the alarm, the existence of which they had never suspected. Then their only safety lay in flight, and they had escaped, leaving behind them the objects I have enumerated. Adams telephoned for the police, while Tucker came up from the Lodge, and I let loose the dogs and went outside into the drive. But, unfortunately, the thieves were already safely away, and were not likely to be caught, for in response to the telephonic message I was told that the rural constable was out on his beat, and was not expected back for another couple of hours. We three men, with several of the maid-servants, stood outside on the lawn discussing the affair with bated breath in the dead stillness of the night when, of a sudden, we distinctly heard in the far distance down in the valley beyond the King's Wood the starting of a motor-car and the gradual faintness of the sound as it receded along the high road. "There they go!" I cried. "They came in a car, and it was awaiting them at the foot of the hill near the Three Oaks crossways." Then I rushed to the telephone instrument and spoke to the police-sergeant on duty in Newport Pagnell, asking him to stop any car approaching from my house, informing him what had occurred. But half an hour later he rang up to tell me that no car had entered the town from any direction; therefore it was apparent that in preference to passing through Newport Pagnell it had been turned into one of the side roads and taken a cross-country route to some unknown destination. I said nothing, but to me it was quite apparent that the object of the attempt upon my safe was the mysterious bronze cylinder, which I held in trust from Melvill Arnold. When alone in the room I opened the safe with my key, and to my satisfaction saw the battered ancient object still reposing there, together with the letters and the translation of the hieroglyphics. Once again I took out the heavy cylinder, the greatest treasure of the strange old fellow who had deliberately destroyed a fortune, and held it in my hand filled with wonder and bewilderment. What could it contain that would astonish the world? Surely nothing nowadays astonishes this matter-of-fact world of ours. We have become used to the demonstrations of wonders, from the use of steam to the development of aviation, the telephonic discovery and the application of wireless telegraphy. How I longed to call in a blacksmith, cut through the metal, and ascertain what was therein contained. But I did not dare. I held the thing in trust for some unknown person who, on Thursday, the third day of November, would come to me and demand its possession.
