Looking back on events by the light of experience I perceive clearly that the thunder-cloud which burst on me and on those who were dear to me had not gathered unseen. It is true that it had rolled up swiftly; that the premonitory mutterings, now so distinct but then so faint and insignificant, gave but a brief warning. But that was of little consequence, since whatever warnings there were passed unheeded, as warnings commonly do, being susceptible of interpretation only by means of the subsequent events which they foreshadowed. The opening scene of the tragedy-if I had but realized it-was the arrival of the Reverend Amos Monkhouse from his far-away Yorkshire parish at the house of his brother Harold. I happened to be there at the time; and though it was not my concern, since Harold had a secretary, I received the clergyman when he was announced. We knew one another well enough by name though we had never met, and it was with some interest and curiosity that I looked at the keen-faced, sturdy, energetic-looking parson and contrasted him with his physically frail and rather characterless brother. He looked at me, too, curiously and with a certain appearance of surprise, which did not diminish when I told him who I was.
