"Yes. You were in a crowd on Reading platform, and were about to enter the same train as myself, but changing your mind, suddenly left the station hurriedly," she said. "At that time, remember, I had no idea that you were in England, for Nelly had not mentioned your visit. Two days later, however, I was appalled by reading in the papers that poor Nelly had been murdered almost immediately after I had left her, and quite close to the spot where we had at first stood. Afterwards in the report of the inquest, I saw that you were present and had given evidence. Then there was silence. The affair was an enigma, and the police possessed no clue. The papers mentioned a broad mark a foot wide upon the dust, which they regarded as mysterious. It was made by my skirt which swept the road. I alone held the key to the enigma. In order to assure myself that my suspicions were not unfounded, I returned to Reading, made careful inquiries there, and when I had satisfied myself, left England with the knowledge I had obtained still in my possession." "What did you discover?" inquired George, quickly, while Liane still clung to him tremblingly. "I discovered absolute proof of the identity of Nolly's assassin. It was Zertho d'Auzac!" CHAPTER TWENTY. AT CROSS LANE. "You lie!" the Prince cried indignantly. "There is no proof." "Listen!" Mariette retorted in a firm, harsh tone, gazing at him steadily. "Listen while I recall to your memory the events of that fateful night. In my inquiries I traced your progress step by step, and every movement is entirely plain to me. You went to England with solely one object in view, namely, to get rid of Nelly Bridson, the woman who could convict you of murder." "I deny that I had any hand whatever in the affair," he protested. "Why, she went with me to the station and saw me off to Reading! It was given in evidence that the police inquired of the station officials at Stratfield Mortimer, and also at Reading, and were entirely satisfied that there was no suspicion upon me. Therefore, whatever you say is utterly worthless," he added, turning from her contemptuously.
