"My dear Major, it is an infallible test. Did you never notice that if you throw anything for a man to catch in his lap, he pulls his knees together to make a lap, in order to catch it; whereas a woman—used to wearing skirts, and thereby having a lap already prepared—simply broadens that lap by the exactly opposite movement, knowing that whatever is thrown has no chance of slipping to the floor. That solved it at once. And now it's bed-time, Major. Good-night."

CHAPTER V

THE RIDDLE OF THE NINTH FINGER

The inn of "The Three Jolly Fishermen," which, as you may know, lies on the left bank of the Thames, within a gunshot of Richmond, was all but empty when Cleek, answering the superintendent's note, strolled into it, and discovered Narkom enjoying his tea in solitary state at a little round table in the embrasure of a bay window at the far end of the little private parlour which lies immediately behind the bar-room.

"My dear fellow, do pardon me for not waiting," said the superintendent, as his famous ally entered, looking like a college-bred athlete in his boating flannels and his brim-tilted panama, "but the fact is, you're a little behind time for once, and besides, I was absolutely famishing."

"Share the blame of my lateness with me, Mr. Narkom," said Cleek, as he tossed aside his hat and threw the fag-end of the cigarette he was smoking out through the open window. "You said in your note that there was no immediate necessity for haste, so I improved the shining hour by another spin down the river. It isn't often that duty-calls bring me to a little Eden like this. The air is like balm to-day, and as for the river—oh, the river is a sheer delight!"

Narkom rang for a fresh pot of tea and a further supply of buttered toast, and, when these were served, Cleek sat down and joined him.

"I dare say," said the superintendent, opening fire at once, "that you wonder what in the world induced me

to bring you out here to meet me, my dear fellow, instead of following the usual course and calling at Clarges Street? Well, the fact is, Cleek, that the gentleman with whom I am now about to put you in touch lives in this vicinity, and is so placed that he cannot get away without running the risk of having the step he is taking discovered."
