throwing me off my guard and taking that way, when he had me alone within his reach. The only means of defence against him on which I could at all rely to lessen the risk, presented themselves, after a little careful thinking, clearly enough. Before I made any personal acknowledgment of my discovery in his presence, I must place the discovery itself where it would be ready for instant use against him, and safe from any attempt at suppression on his part. If I laid the mine under his feet before I approached him, and if I left instructions with a third person to fire it on the expiration of a certain time, unless directions to the contrary were previously received under my own hand, or from my own lips—in that event the Count's security was absolutely dependent upon mine, and I might hold the vantage ground over him securely, even in his own house.
This idea occurred to me when I was close to the new lodgings which we had taken on returning from the sea-side. I went in without disturbing any one, by the help of my key.

If you do not hear from me, or see me, before that time, break the seal when the clock strikes, and read the contents." I added my initials, and protected the whole by enclosing it in a second sealed envelope, addressed to Pesca at his lodgings.
Nothing remained to be done after this but to find the means of sending my letter to its destination immediately. I should then have accomplished all that lay in my power. If a
