Raffles’s plan was to gain access to Lord Ernest’s rooms before midnight; there we were to lie in wait for the aristocratic rascal, and if I left all details to Raffles, and simply stood by in case of a rumpus, I should be playing my part and earning my share. It was a part that I had played before, not always with a good grace, though there had never been any question about the share. But to-night I was nothing loath. I had had just champagne enough—how Raffles knew my measure!—and I was ready and eager for anything. Indeed, I did not wish to wait for the coffee, which was to be especially strong by order of Raffles. But on that he insisted, and it was between ten and eleven when at last we were in our cab. “It would be fatal to be too early,” he said as we drove; “on the other hand, it would be dangerous to leave it too late. One must risk something. How I should love to drive down Piccadilly and see the lights! But unnecessary risks are another story.” II King John’s Mansions, as everybody knows, are the oldest, the ugliest, and the tallest block of flats in all London. But they are built upon a more generous scale than has since become the rule, and with a less studious regard for the economy of space. We were about to drive into the spacious courtyard when the gate-keeper checked us in order to let another hansom drive out. It contained a middle-aged man of the military type, like ourselves in evening dress. That much I saw as his hansom crossed our bows, because I could not help seeing it, but I should not have given the incident a second thought if it had not been for his extraordinary effect upon Raffles. In an instant he was out upon the curb, paying the cabby, and in another he was leading me across the street, away from the mansions. “Where on earth are you going?” I naturally exclaimed. “Into the park,” said he. “We are too early.” His voice told me more than his words. It was strangely stern. “Was that him—in the hansom?” “It was.” “Well, then, the coast’s clear,” said I, comfortably. I was for turning back then and there, but Raffles forced me on with a hand that hardened on my arm. “It was a nearer thing than I care about,” said he. “This seat will do; no, the next one’s further from a lamp-post. We will give him a good half-hour, and I don’t want to talk.” We had been seated some minutes when Big Ben sent a languid chime over our heads to the stars. It was half-past ten, and a sultry night. Eleven had struck before Raffles awoke from his sullen reverie, and recalled me from mine with a slap on the back. In a couple of minutes we were in the lighted vestibule at the inner end of the courtyard of King John’s Mansions. “Just left Lord Ernest at Lady Kirkleatham’s,” said Raffles. “Gave me his key and asked us to wait for him in his rooms. Will you send us up in the lift?”
