The rain soon fell faster and thicker. We had no umbrellas; and being by this time in a region of back-streets, an empty fiacre was a prize not to be hoped for. Coming presently to a dark archway, we took shelter and waited till the shower should pass over. It lasted longer than we had expected, and threatened to settle into a night's steady rain. Müller kept his blood warm by practicing extravagant quadrille steps and singing scraps of Béranger's ballads; whilst I, watching impatiently for a cab, kept peering up and down the street, and listening to every sound.

Presently a quick footfall echoed along the wet pavement, and the figure of a man, dimly seen by the blurred light of the street-lamps, came hurrying along the other side of the way. Something in the firm free step, in the upright carriage, in the height and build of the passer-by, arrested my attention. He drew nearer. He passed under the lamp just opposite, and, as he passed, flung away the end of his cigar, which fell, hissing, into the little rain-torrent running down the middle of the street. He carried no umbrella; but his hat was pulled low, and his collar drawn up, and I could see nothing of his face. But the gesture was enough.

For a moment I stood still and looked after him; then, calling to Müller that I should be back presently, I darted off in pursuit.


CHAPTER XLIX.

THE KING OF DIAMONDS.

The rain beat in my face and almost blinded me, the wind hustled me; the gendarme at the corner of the street looked at me suspiciously; and still I followed, and still the tall stranger strode on ahead. Up one street he led me and down another, across a market-place, through an arcade, past the Bourse, and into that labyrinth of small streets that lies behind the Italian Opera-house, and is bounded on the East by the Rue de Richelieu, and on the West by the Rue Louis le Grand. Here he slackened his pace, and I found myself gaming upon him for the first time. Presently he came to a dead stop, and as I continued to draw nearer, I saw him take out his watch and look at it by the light of a street-lamp. This done, he began sauntering slowly backwards and forwards, as if waiting for some second person.

For a moment I also paused, hesitating. What should I do?--pass him under the lamp, and try to see his face? Go boldly up to him, and invent some pretence to address him, or wait in this angle of deep shade, and see what would happen next? I was deceived, of course--deceived by a merely accidental resemblance. Well, then, I should have had my run for my pains, and have taken cold, most likely, into the bargain. At all events, I would speak to him.

Seeing me emerge from the darkness, and cross over towards the spot where he was standing, he drew aside with the air of a man upon his guard, and put his hand quickly into his breast.

"I beg your pardon, Monsieur," I began.
