In days to come, when the boy had schooled himself not to speak of these days, nor to let his mind dwell on their mystery and terror, it was as a day of dark hours and vivid moments that he remembered the one which Phillida and he began alone together in her uncle’s house. Those endless hours were either mercifully forgotten or else contracted to an endurable minimum; but the unforgettable moments would light themselves up in his memory without a detail missing.

There was their first encounter at the dark-room door, and Phillida standing all but barefoot in the ruby light, with her glorious hair about her shoulders, a picture that could never fade. Then there was the moment of the incriminating print, which the sun wiped out even as Phillida stood with it in her hands. That moment merged itself in the greater one of his discovery that the revolver was fully loaded, his inspiration that neither it nor he had done the fatal mischief in the Park. Then she was begging him to go (she who would keep him the time before!) and he entreating her to come with him, and neither giving way an inch, so that they quarrelled just when they should have stuck together, and she ran away in tears, and he stayed below in a glow of anger which dissolved his fears like snow in May.

That was the beginning of a black hour and more. Phillida was never to be forgiven, then; he was staying there at his peril, staying absolutely on her account, and so far from giving him the slightest credit for it, or a single word of encouragement, she said all sorts of things and was off before he could answer one of them. It was not for Pocket to see the many ironies of that moment, and not for him to recognise the tonic property of his heroic grievance. He could only see himself at the foot of those stairs, first gnashing his teeth and not sorry he had made her cry, then sitting down with his eye on the front door, revolver in hand, to await the click of the doctor’s key. Another click was to answer it; and at the point of the cocked revolver Baumgartner was to have made a clean breast of his crimes, not only to the giant-killer at the foot of the stairs but to the girl he meant to call to witness with her own ears.

Pocket saw himself a desperate character just then, and one not incapable of desperate action had the climax only come at once. But he had more than an hour of it alone at his post; he had a whole hot forenoon of unmitigated suspense, of sickening alarms from tradesmen’s carts, boys whistling past the house as though they were not in a wicked world at all, and then a piano-organ that redoubled his watchfulness, and spoilt some tunes for him for ever. Once he did hear shambling feet on the very steps outside. Once was quite enough, though it was but an advertisement for cast-off clothing (and false teeth) that came fluttering through the letter-box. Pocket was left in such a state that he would not have backed himself to hit the door from the stairs; and he put the chain on it, thinking to interview the doctor over that, in the manner of old Miss Harbottle.

So it happened that the first significant sound was entirely lost upon him, because he was listening for one so much nearer at hand, until Phillida ran downstairs and almost over him where he sat.

He got up to make way stiffly, but a glance assured him that the quarrel was over on her side. The great eyes were fixed appealingly upon him, but with a distressing look which he had done nothing to provoke. Not before then was he aware of another duet between newsboys coming nearer and nearer, and shouting each other down as they came.

“You hear that?” she whispered, as if not to drown a note.

“I do now.”

“Do you hear what it is?”

Pocket listened, and caught a word he was not likely to miss.
