In and out of the maze of ancient streets that are Old Geneva, to and fro along the alleys that lead through balconied, leaning houses, up and down obscure and sudden flights of stone steps, Henry wandered under the September moon. All day he had, with the help of Charles Wilbraham's unwitting secretary, tracked Charles Wilbraham. He knew how Charles had begun the morning by dictating proud and ponderous documents in his proud and ponderous voice, and talking to people who came in and out of his room; how he had then gone to the Assembly Hall and chatted in the lobby to every one of sufficient importance to be worth his while, including ex-Cardinal Franchi, who had of late been making friends with him, and with whom he had dined last night at the ChÂteau LÉman; how then Charles had lunched with two Russians, a Greek, and a Pole, and Sir John Levis, his father-in-law, at the CafÉ du Nord, hatching Henry did not know what (for the Nord was much too expensive for him) of anti-League mischief and crime; how after lunch Charles had attended the meetings of the sub-committees on the Disappearance of Delegates, going from one to another looking business-like and smug and as if he were at strictly private meetings, as indeed he was. Then up to his room for his tea (Charles never missed this meal) and down again to see how Sub-Committee 5 (“Consideration of Various Suspicions based on Reason and Common Sense”) was getting on, and then up again to do some more work. (For there was this about Charles, as even Henry had to admit—he worked hard. Ambition, the last infirmity of noble minds, offensive and irritating quality as it is, has at least this one good fruit.) Then Charles had been to a large dinner given by the Canadian delegation to members of the Secretariat, and had made a facetious speech; and now, at eleven-thirty, he was walking about the old city, followed at some distance by Henry Beechtree.

Charles was not alone. He had with him M. Kratzky from Russia, Sir John Levis, and a small, quiet Calvinist minister, whom Henry had lately seen about Geneva.

The four gentlemen turned out of the Rue du Perron down the narrow, ancient and curious Passage de Monnetier, and out of that into a deep arched alley running through a house into another street. Henry, watching from the corner of the Passage de Monnetier, did not dare to follow nearer for some moments. When he had given them a little time, he softly tiptoed to the mouth of the alley. It was one of those deep cobbled passages that run through many houses in the old quarter. It was profoundly dark; Henry could only faintly discern the three figures half-way down it. They seemed to have stopped, and to be bending down as if looking for something on the ground. The spark of an electric torch gleamed suddenly, directed by the little clergyman; its faint disc of light swam over the dirty floor of the passage, till it came to rest on an iron ring that lay flat to the ground. The clergyman seized this ring and jerked at it; after a moment it left the ground in his hand, and with it the flap of a trap-door.

Whispers inaudible to Henry passed between the members of the party; then, one by one, the three figures descended through the open trap into the bowels of the earth, and the lid closed upon them.

Henry tiptoed forward; should he follow? On the whole—no. On the whole he would wait until Wilbraham, his father-in-law, M. Kratzky, and the clergyman emerged. What, after all, would be the use of finding oneself underground with desperate, detected criminals, whose habit it apparently was to stick at nothing? What, after all, could he do?

Henry was shivering, less from fear than excitement. Here, indeed, was a clue. Were they kept immured underground, these unfortunate captive delegates? And did Wilbraham and his criminal associates visit them from time to time with food and drink? Or without? With nothing, perhaps, but taunts? And how many more in Geneva knew of this trap-door and its secret? There were, every one knew, a number of these old trappons in the city, leading usually to disused cellars; their presence excited no suspicion. Probably no one ever used the obscure and hidden trap in this dark alley.

It was queer, how sure Henry felt that this curious nocturnal expedition on the part of Charles, his father-in-law, M. Kratzky and the Calvinist pastor had to do with the mystery of the delegates. He knew it beyond a doubt. Nor was he surprised. It came as a consummation of his suspicion and his hopes. Of Charles Wilbraham's villainy he had long been all but sure; of the villainy of M. Kratzky all the world knew; of the villainy of an ammunitions knight and a Calvinist pastor there needed little to convince Henry. But he knew that he must make sure. He must not go to the police, or to the committee, with an unproved tale. He must wait and investigate and prove.

He waited, in the dark archway beneath the crazy jumble of houses, with the sudden voices and footfalls of the midnight city echoing from time to time in the dark streets beyond. He waited and waited and waited. Now and then a dog or a cat rushed by him, startling him. Then, after twenty minutes or so, he wearied of waiting. Weariness and curiosity defeated caution; he pulled up the trap-door by its ring and peered down into blackness. Blackness, stillness, emptiness, and a queer, mouldy smell. Henry sat on the hole's edge for a full minute, dangling his legs. Then, catching his breath a little (it may or may not have been mentioned that Henry was not very brave), he swung himself down on to a hard, earthy floor.

It was a tunnel he was in; a passage about six feet high and four feet wide. How many feet or yards long was a more difficult and a much more interesting question. Feet? Yards? It might be miles. Henry's imagination bored through the impenetrable dark in front of the little moon thrown by his electric torch; through and along, through and along, towards what? The horrid four who had preceded him—where were they? Did they lurk, planning some evil, farther along the tunnel, just out of earshot? Or had they emerged by some other exit? Or were they even now returning, to meet Henry in a moment face to face, to brush by him as he pressed against the damp brick wall, to turn on him suddenly that swimming moon of light ... and then what?

Charles Wilbraham was no taker of human life, Henry felt assured. He was too prudent, too respectable, too much the civil servant. M. Kratzky, on the other hand, was a taker of human life—he did it as naturally as others would slay midges; while he breathed he slew. If Henry should be discovered spying, M. Kratzky's counsels would be all for making forthwith an end of Henry. Sir John Levis was an armament knight: members of the staff of the British Bolshevist needed not to know more of him than that: the Calvinist minister was either a Calvinist minister, and that was bad, or a master-criminal of the underworld disguised as a Calvinist minister, and that was worse. Or both of these. Four master-criminals of the underworld—these intriguing, appalling creatures, so common in the best fiction, so rare even in the worst life—if one were to meet four of them together in a subterranean passage.... Could human flesh and nerves endure it?

Henry, with his shuddering dislike of seeing even a goldfish injured or slain, shrank far more shudderingly from being injured or slain himself. The horrid wrench that physical assault was—and then, perhaps, the sharp break with life, the plunge into a blank unknown—and never to see again on this earth the person whom one very greatly loved....

As has been said, Henry was not brave. But he was, after all, a journalist on the scent of a story, and that takes one far; he was also a hunter in pursuit of a hated quarry, and that takes one farther.

Henry crossed himself, muttered a prayer and advanced down the passage, his torch a lantern before his feet, his nerves shivering like telegraph wires in a winter wind, but fortunately not making the same sound.
