At that particular moment Mr. Central Detective Inspector Carn and his posse were plodding wearily through the darkness towards Baycombe, their car having broken down with twelve miles still to go, and the prospects of getting a lift on that lonely road, at that hour of the night, being exactly _nil_. Chapter XVI In the Swim To fall one hundred and sixty feet takes just a shade over three seconds, but it seems a lot longer. Simon Templar knew this very vividly, for he seemed to live through three æons between the instant of sickening breathlessness when he felt the cut-away flooring give way under his weight, through the four odd pulse-beats of hurtling down and down into darkness, till he struck water with a stinging splash. He sank like a plummet, and struck out mightily for the surface. He must have gone deep, for by the time his head came up his heart was pounding furiously and his chest felt as if it was about to cave in under the pressure. He drew a giant’s breath, and choked at the end of it, for, unsuspecting, he had let himself be sucked under again. The undertow was terrific. He kicked out with all his strength, and as he rose again, gasping and spitting, his hand touched stone and got a grip on it instinctively. In spite of his experience, he still misjudged the power of the current: his hold was all but broken as soon as he obtained it, and his arm was nearly jerked from its socket with the strain. With an exertion of every bit of force he could rally he drew himself up with his shoulder muscles, thrashing the water with his legs, until he got the fingers of his other hand crooked over that providential ledge. There he hung, panting, with the sinews of his arms taut and creaking, while he shook the water out of his eyes and tried to get his bearings. Already he had been swept some distance from where he had fallen—it must have been a longish way, reckoning by the force of the stream as measured by the pull on his arms. The blackness was not complete, fortunately. His eyes were already used to the darkness, and so he was able to take in the surroundings comparatively well by the faint phosphorescent light which filtered up, apparently, from the surface of the water.
