streets of the East side, I began to scent whom the prey might be that he was seeking, and putting every other consideration aside, regularly set myself to dog his steps, as only I, with my innumerable disguises, knew how to do. For three separate days I kept at his heels wherever he went, each day growing more and more astonished if not to say hopeful, as I found myself treading the narrowest and most disreputable streets of the city; halting at the shops of pawnbrokers; peering into the back-rooms of liquor shops; mixing with the crowds that infest the corner groceries at nightfall, and even slinking with hand on the trigger of the pistol I carried in my pocket, up dark alleys where every door that swung noiselessly to and fro as we passed, shut upon haunts of such villainy as only is known to us of the police, or to those good souls that for the sake of One whose example they follow, lay aside their fears and sensitiveness to carry light into the dim pits of this wretched world. At first I thought Mr. Blake might have some such reason for the peculiar course he took. But his indifference to all crowds where only men were collected, his silence where a word would have been well received, convinced me it was a woman he was seeking and that with an intentness which blinded him to the commonest needs of the hour. I even saw him once in his hurry and abstraction, step across the body of a child who had fallen face downward on the stones, and that with an expression showing he was utterly unconscious of anything but an obstacle in his path.

Perhaps, like me, he carried a pistol. At all events he shunned no spot where either poverty lay hid or deviltry reigned, his proud stern head bending to enter the lowest doors without a tremble of the haughty lips that remained compressed as by an iron force; except when some poor forlorn creature with flaunting head-gear, and tremulous hands, attracted by his bearing would hastily brush against him, when he would turn and look, perhaps speak, though what he said I always failed to catch; after which he would hurry on as if possessed by seven devils. The evenings of those three days were notable also. Two of them he spent in the manner I have described; the third he went to the Windsor House--where the Countess De Mirac had taken rooms--going up to the ladies' entrance and actually ringing the bell, only to start back and walk up and down on the opposite side of the way, with his hands
