"Or any reason to fear Countess Lukstein?"
"None," I replied again; but after a moment's thought I added: "But she did fear her. I am sure of it."
He sprang to his feet.
"Three days!" he cried. "Three days! We may yet outwit him."
"How?" I asked, with the greatest eagerness.
"I'll not tell you now. 'Tis no more than a fancy. Wait you here your three days. Keep a strict watch on Marston's house. 'Tis unlikely that he will move before the time, since he would rather you spared him the telling of the story; but there's no trusting him. On Thursday I will come to you here before midnight; so wait for me, unless, of course, Marston leaves before then. In that case, follow him, but send word here of your direction. You must be wary; the fellow's cunning, and may get free from his house in some disguise."
With that he clapped his hat on his head, and rushed out into the street. For the next three days I saw no more of him. About Marston's house I kept strict watch as he enjoined. There were but two entrances: one in the façade of the building towards the Square, and the second in a little side-street which ran along a wall of the house. Few, however, either came in or out of these entrances, for the rumour of his sickness was spread abroad in the town, and even his tradesmen dreaded to catch the infection. I was, moreover, certain that he had not escaped, since each evening his servant came to my lodging and left a stick notched according to the number of days.
On the morning of the Thursday, being the fourth day and my last of grace, I doubled the sentinels about the house, hiring for the purpose some fellows of whom my people had cognizance. At the entrances, however, I planted my own men, and bidding them mark carefully the faces of such as passed out, in whatever dress they might be clothed, I retired to a coign of vantage at some distance whence I could keep an eye upon the house, and yet not obtrude myself upon the notice of those within it. In a little alley hard by I had stationed a groom with the swiftest horse that I possessed, so that I might be prepared to set off in pursuit of my antagonist the moment word of his departure was brought to me.
Thus, then, I waited, my heart throbbing faster and faster as the day wore on, and every nerve in my body a jerking pulse. At last my excitement mastered me; a clock in a neighbouring belfry chimed the hour of four, and I crept out of my corner and mingled with the gipsies and mountebanks who were encamped with their booths in the centre of the Square. Amongst this motley crowd I thought myself safe from detection, and moved, though still observing some caution, towards the front of Marston's house. It wore almost an air of desertion; over many of the windows the curtains were drawn, and never a face showed through the panes of the rest. I could see that my men were still stationed at their posts, and I began to think that we must needs prolong our vigil into the night. Shortly after six, however, the hall-door was opened, and the same servant who brought me the sticks of an evening came out on to the steps. He looked neither to the right nor to the left, but without a moment's hesitation stepped across the road, and threading the tents and booths, came directly towards me. It was evident that I had been remarked from some quarter of the house, and so I made no effort at further concealment, but rather went forward to meet him. With the same grave politeness which had always characterised him, he offered me a letter.
"My master," said he, "bade me deliver this into your hand two hours after he had left."
