finding me a messenger. He happened to be ascending the stairs at the time, and we met on the landing. His son, a quick lad, was the messenger he proposed to me on hearing what I wanted. We had the boy upstairs, and I gave him his directions. He was to take the letter in a cab, to put it into Professor Pesca’s own hands, and to bring me back a line of acknowledgment from that gentleman—returning in the cab, and keeping it at the door for my use. It was then nearly half-past ten. I calculated that the boy might be back in twenty minutes, and that I might drive to St. John’s Wood, on his return, in twenty minutes more.
When the lad had departed on his errand I returned to my own room for a little while, to put certain papers in order, so that they might be easily found in case of the worst. The key of the old-fashioned bureau in which the papers were kept I sealed up, and left it on my table, with Marian’s name written on the outside of the little packet. This done, I went downstairs to the sitting-room, in which I expected to find Laura and Marian awaiting my return from the Opera. I felt my hand trembling for the first time when I laid it on the lock of the door.
