He pressed close up to Peter, held both his hands in his and said: “Look 'ere, Peter boy, yer may be wanting me soon--no, I can't say more than that. But I want yer--to be on the look-out. Down there at the bookshop be ready, and then if any sort o' thing should 'appen down along--why I'm there, d'ye see? I'll be with yer when you want me--” “Well, but Stephen, what do you mean? What _could_ happen? Anyhow you mustn't go now, like this. I won't let you go--” “Ah, but I must now--I must. Maybe we shall be meeting soon enough. Only I'm there, boy, if yer wants me. And--keep yer eye open--” In an instant that warm pressure of the hand was gone; the darker black of Stephen's body no longer silhouetted against the lighter black of the night sky. Still in Peter's nose there was that scent of wet clothes and the deep, husky voice was in his ears. But, save for the faint yellow flickering lamp, struggling against the tempest, he was alone in the square. The rain had begun to fall again. CHAPTER II THE MAN ON THE LION I After the storm, the Fog. It came, a yellow, shrouded witch down upon the town, clinging, choking, writhing, and bringing in its train a thousand mysteries, a thousand visions. It was many years since so dense and cruel a fog had startled London--in his seven years' experience of the place Peter had known nothing like it, and his mind flew back to that afternoon of his arrival, seven years before, and it seemed to him that he was now moving straight on from that point and that there had been no intervening period at all. The Signer saw in a fog as a cat sees in the dark, and he led Peter to the bookshop without hesitation. He saw a good many other things beside his immediate direction and became comparatively cheerful and happy. “It is such a good thing that people can't see me,” he said. “It relieves one of a lot of responsibility if one's plain to look at--one can act more freely.” Certainly the Signor acted with very considerable freedom, darting off suddenly into the fog, apparently with the intention of speaking to some one, and leaving Peter perfectly helpless and then suddenly darting back again, catching Peter in tow and tugging him forward once more. To the bookshop itself the fog made very little difference. There were always the gas-jets burning over the two dark corners and the top shelves even in the brightest of weather, were mistily shrouded by dust and distance. The fog indeed seemed to bring the books out and, whilst the world outside was so dark, the little shop flickered away under the gas-jets with little spasmodic leaps into light and colour when the door opened and blew the quivering flame.
