It was the expression on the man’s countenance, as much as anything else, which made me behave as I did. I said something to him,—some nonsense, I know not what. He regarded me with a silence which was supernatural. I spoke to him again;—not a word issued from those rigid lips; there was not a tremor of those awful eyes,—eyes which I was tolerably convinced saw something which I had never seen, or ever should. Then I took my hand from off his shoulder, and let him go. I know not why,—I did.

He had remained as motionless as a statue while I held him,—indeed, for any evidence of life he gave, he might have been a statue; but, when my grasp was loosed, how he ran! He had turned the corner and was out of sight before I could say, ‘How do!’

It was only then,—when he had gone, and I had realised the extra-double-express-flash-of-lightning rate at which he had taken his departure—that it occurred to me of what an extremely sensible act I had been guilty in letting him go at all. Here was an individual who had been committing burglary, or something very like it, in the house of a budding cabinet minister, and who had tumbled plump into my arms, so that all I had to do was to call a policeman and get him quodded,—and all that I had done was something of a totally different kind.

‘You’re a nice type of an ideal citizen!’ I was addressing myself. ‘A first chop specimen of a low-down idiot,—to connive at the escape of the robber who’s been robbing Paul. Since you’ve let the villain go, the least you can do is to leave a card on the Apostle, and inquire how he’s feeling.’

I went to Lessingham’s front door and knocked,—I knocked once, I knocked twice, I knocked thrice, and the third time, I give you my word, I made the echoes ring,—but still there was not a soul that answered.

‘If this is a case of a seven or seventy-fold murder, and the gentleman in the cloak has made a fair clearance of every living creature the house contains, perhaps it’s just as well I’ve chanced upon the scene,—still I do think that one of the corpses might get up to answer the door. If it is possible to make noise enough to waken the dead, you bet I’m on to it.’

And I was,—I punished that knocker! until I warrant the pounding I gave it was audible on the other side of Green Park. And, at last, I woke the dead,—or, rather, I roused Matthews to a consciousness that something was going on. Opening the door about six inches, through the interstice he protruded his ancient nose.

‘Who’s there?’

‘Nothing, my dear sir, nothing and no one. It must have been your vigorous imagination which induced you to suppose that there was,—you let it run away with you.’

Then he knew me,—and opened the door about two feet.
