My notion was that the proceedings of the persons in Mrs. Crosscapel's house had not been closely enough inquired into yet. By way of continuing the investigation, I asked Priscilla if she could tell me anything which associated the housemaid with Mr. Deluc. She was unwilling to answer. "I may be casting suspicion on an innocent person," she said. "Besides, I was for so short a time the housemaid's fellow servant--" "You slept in the same room with her," I remarked; "and you had opportunities of observing her conduct toward the lodgers. If they had asked you, at the examination, what I now ask, you would have answered as an honest woman." To this argument she yielded. I heard from her certain particulars, which threw a new light on Mr. Deluc, and on the case generally. On that information I acted. It was slow work, owing to the claims on me of my regular duties; but with Priscilla's help, I steadily advanced toward the end I had in view. Besides this, I owed another obligation to Mrs. Crosscapel's nice-looking cook. The confession must be made sooner or later--and I may as well make it now. I first knew what love was, thanks to Priscilla. I had delicious kisses, thanks to Priscilla. And, when I asked if she would marry me, she didn't say No. She looked, I must own, a little sadly, and she said: "How can two such poor people as we are ever hope to marry?" To this I answered: "It won't be long before I lay my hand on the clew which my Inspector has failed to find. I shall be in a position to marry you, my dear, when that time comes." At our next meeting we spoke of her parents. I was now her promised husband. Judging by what I had heard of the proceedings of other people in my position, it seemed to be only right that I should be made known to her father and mother. She entirely agreed with me; and she wrote home that day to tell them to expect us at the end of the week. I took my turn of night-duty, and so gained my liberty for the greater part of the next day. I dressed myself in plain clothes, and we took our tickets on the railway for Yateland, being the nearest station to the village in which Priscilla's parents lived. VI. THE train stopped, as usual, at the big town of Waterbank. Supporting herself by her needle, while she was still unprovided with a situation, Priscilla had been at work late in the night--she was tired and thirsty. I left the carriage to get her some soda-water. The stupid girl in the refreshment room failed to pull the cork out of the bottle, and refused to let me help her. She took a corkscrew, and used it crookedly. I lost all patience, and snatched the bottle out of her hand. Just as I drew the cork, the bell rang on the platform. I only waited to pour the soda-water into a glass--but the train was moving as I left the refreshment room. The porters stopped me when I tried to jump on to the step of the carriage. I was left behind.
