The chances against me wanted no reckoning up⁠—they were all merged in one. If the Count discovered, by my own avowal, that the direct way to his safety lay through my life, he was probably the last man in existence who would shrink from 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.
