"We shall see," she replied. "If you have so conveniently forgotten what your movements were, I will describe them. It is quite true that Nelly saw you off to Reading. But prior to this, while alone in the dining-room of Captain Brooker's cottage, you found lying about the letter I had written her making the appointment. Curiosity prompted you to read its contents, and you therefore knew that at seven o'clock she would be in Cross Lane. You bade her farewell at eight minutes past six, and your train arrived at Reading at twenty minutes past. You immediately took a fly back towards Stratfield, but dismissed the man at Threemile Cross, and after watching the conveyance out of sight, took a cut across the fields for about a mile and a half to Cross Lane, thus completely doubling. It was growing dark when you reached the railway bridge, but you saw your victim coming from the opposite direction, and drew back half-way up the steep ascent, where you knew she must pass slowly. Suspecting no danger, the light-hearted girl allowed her machine to run swiftly down the incline, then pedalled hard for the ascent, when suddenly you raised your weapon, took deliberate aim and fired. With a cry she dropped sideways on her feet, the machine falling with her. Then she blindly staggered forward two or three paces, and sank to earth, dying. For an instant you waited, but even while you looked the poor girl sighed heavily and passed away. Then, fearing detection, you turned and fled back across the fields to Reading station, where I saw you an hour later." "It's an absolute falsehood!" he cried. "I went direct to London after leaving the girl." "You did not, for I found the man who drove you to Threemile Cross, and who will give evidence against you on your trial." "You have!" he gasped. "You will hand me over to the police?" he added hoarsely. "Certainly," she answered, firmly. "The police of Reading and the police of Nice will alike be anxious to give you free lodgings in a chamber scarcely as comfortable as any in the Villa Chevrier. For a good many months the mystery of Charles Holroyde's death has puzzled them, but it will remain an enigma no longer." "Then Brooker will suffer also," he cried. "No, he will not," replied the inventor of "The Agony of Monte Carlo," quickly. "My evidence will prevent that. I saw you commit the murder, and likewise witnessed how Brooker endeavoured to prevent you." "Again," cried Mariette, "there is yet another fact. From inquiries I have made it is plain that some months prior to Nelly's death she, by word or action, had betrayed her knowledge of your crime committed in Nice."
