“A solitary fly, the last of his race whom the winter had spared, was buzzing feebly about the doctor’s face. He caught it before he answered me, and held it out across the table in his closed hand.
“‘If this fly’s name was Armadale,’ he said, ‘and if you had got him as I have got him now, what would you do?’
“His eyes, fixed on my face up to this time, turned significantly, as he ended this question, to my widow’s dress. I, too, looked at it when he looked. A thrill of the old deadly hatred and the old deadly determination ran through me again.
“‘I should kill him,’ I said.
“The doctor started to his feet (with the fly still in his hand), and looked at me—a little too theatrically—with an expression of the utmost horror.
“‘Kill him!’ repeated the doctor, in a paroxysm of virtuous alarm. ‘Violence—murderous violence—in My Sanitarium! You take my breath away!’
“I caught his eye while he was expressing himself in this elaborately indignant manner, scrutinizing me with a searching curiosity which was, to say the least of it, a little at variance with the vehemence of his language and the warmth of his tone. He laughed uneasily when our eyes met, and recovered his smoothly confidential manner in the instant that elapsed before he spoke again.
“‘I beg a thousand pardons,’ he said. ‘I ought to have known better than to take a lady too literally at her word. Permit me to remind you, however, that the circumstances are too serious for anything in the nature of—let us say, an exaggeration or a joke. You shall hear what I propose, without further preface.’ He paused, and resumed his figurative use of the fly imprisoned in his hand. ‘Here is Mr. Armadale. I can let him out, or keep him in, just as I please—and he knows it. I say to him,’ continued the doctor, facetiously addressing the fly, ‘Give me proper security, Mr. Armadale, that no proceedings of any sort shall be taken against either this lady or myself, and I will let you out of the hollow of my hand. Refuse—and, be the risk what it may, I will keep you in.” Can you doubt, my dear madam, what Mr. Armadale’s answer is, sooner or later, certain to be? Can you doubt,’ said the doctor, suiting the action to the word, and letting the fly go, ‘that it will end to the entire satisfaction of all parties, in this way?’
“‘I won’t say at present,’ I answered, ‘whether I doubt or not. Let me make sure that I understand you first. You propose, if I am not mistaken, to shut the doors of this place on Mr. Armadale, and not to let him out again until he has agreed to the terms which it is our interest to impose on him? May I ask, in that case, how you mean to make him walk into the trap that you have set for him here?’
“‘I propose,’ said the doctor, with his hand on the railway guide, ‘ascertaining first at what time during every evening of this month the tidal trains from Dover and Folkestone reach the London Bridge terminus. And I propose, next, posting a person whom Mr. Armadale knows, and whom you and I can trust, to wait the arrival of the trains, and to meet our man at the moment when he steps out of the railway carriage.’
