This command—given in a mild conversational tone—was not answered with the expected hellish noises and exhalations. He peeled his eye from the lens and was abruptly reminded that he was two hundred feet above London. A bad time for a dizzy spell. He spanked the railing, clenched his eyes shut, and announced: "The Scotsman is inside the White Tower; I say, Fire!" Then he opened his eyes, got up, and backed round the stony bole of the Monument, for these things were as likely to explode as to fly. He heard Jimmy and Danny murmuring to each other, then a sputter as the fuse caught, then running feet. The lads came into view. Immediately a basilisk-sound, half hiss and half scream, erupted on the other side and rapidly dwindled.
