When Adam got home after his walk, he found Sir Nathaniel just going to bed. He did not say anything to him then of what had happened, but contented himself with arranging that they would walk together in the early morning, as he had much to say that would require serious attention. Strangely enough he slept well, and awoke at dawn with his mind clear and his nerves in their usual unshaken condition. The maid brought up, with his early morning cup of tea, a note which had been found in the letter- box. It was from Lady Arabella, and was evidently intended to put him on his guard as to what he should say about the previous evening. He read it over carefully several times, before he was satisfied that he had taken in its full import. "DEAR MR. SALTON, "I cannot go to bed until I have written to you, so you must forgive me if I disturb you, and at an unseemly time. Indeed, you must also forgive me if, in trying to do what is right, I err in saying too much or too little. The fact is that I am quite upset and unnerved by all that has happened in this terrible night. I find it difficult even to write; my hands shake so that they are not under control, and I am trembling all over with memory of the horrors we saw enacted before our eyes. I am grieved beyond measure that I should be, however remotely, a cause of this horror coming on you. Forgive me if you can, and do not think too hardly of me. This I ask with confidence, for since we shared together the danger--the very pangs--of death, I feel that we should be to one another something more than mere friends, that I may lean on you and trust you, assured that your sympathy and pity are for me. You really must let me thank you for the friendliness, the help, the confidence, the real aid at a time of deadly danger and deadly fear which you showed me. That awful man--I shall see him for ever in my dreams. His black, malignant face will shut out all memory of sunshine and happiness. I shall eternally see his evil eyes as he threw himself into that well-hole in a vain effort to escape from the consequences of his own misdoing. The more I think of it, the more apparent it seems to me that he had premeditated the whole thing--of course, except his own horrible death.
