Lucile deliberately took her seat at my desk, and seizing a pen hastily affixed her signature to the agreement, and rising, left the office without uttering another syllable. "I have, at least, the paper," thought I, "and that I intend to keep." My plans were soon laid. I sat down and addressed a most pressing letter to Mr. Courtland, informing him fully of the plot of the lunatic, for so I then regarded him, and urged him to hasten to San Francisco without a moment's delay. Then, seizing my hat, I made a most informal call on Dr. White, and consulted him as to the best means of breaking through the conspiracy. We agreed at once that, as Pollexfen had committed no overt act in violation of law, he could not be legally arrested, but that information must be lodged with the chief of police, requesting him to detail a trustworthy officer, whose duty it should be to obey us implicitly, and be ready to act at a moment's notice. All this was done, and the officer duly assigned for duty. His name was Cloudsdale. We explained to him fully the nature of the business intrusted to his keeping, and took great pains to impress upon him the necessity of vigilance and fidelity. He entered into the scheme with alacrity, and was most profuse in his promises. Our settled plan was to meet at the outer door of the photographer's gallery, at half-past ten o'clock P. M., on the 19th of November, 1853, and shortly afterwards to make our way, by stratagem or force, into the presence of Pollexfen, and arrest him on the spot. We hoped to find such preparations on hand as would justify the arrest, and secure his punishment. If not, Lucile was to be removed, at all events, and conducted to a place of safety. Such was the general outline. During the week we had frequent conferences, and Cloudsdale effected an entrance, on two occasions, upon some slight pretext, into the room of the artist. But he could discover nothing to arouse suspicion; so, at least, he informed us. During the morning of the 19th, a warrant of arrest was duly issued, and lodged in the hands of Cloudsdale for execution. He then bade us good morning, and urged us to be promptly on the ground at half-past ten. He told us that he had another arrest to make on the Sacramento boat, when she arrived, but would not be detained five minutes at the police office. This was annoying, but we submitted with the best grace possible. During the afternoon, I got another glimpse at our "trusty." The steamer left for Panama at one P. M., and I went on board to bid adieu to a friend who was a passenger. Cloudsdale was also there, and seemed anxious and restive. He told me that he was on the lookout for a highway robber, who had been tracked to the city, and it might be possible that he was stowed away secretly on the ship. Having business up town, I soon left, and went away with a heavy heart.
