Armitage, following at twenty yards on the opposite side of the street, paused abruptly at the sudden ending of his chase.  It was not an hour for loitering, for the Genevan gendarmerie have rather good eyes, but Armitage had by no means satisfied his curiosity as to the nature of Chauvenet’s errand.  He walked on to make sure he was unobserved, crossed the street, and again passed the dark, silent house which Chauvenet had entered.  He noted the place carefully; it gave no outward appearance of being occupied.  He assumed, from the general plan of the neighboring buildings, that there was a courtyard at the rear of the darkened house, accessible through a narrow passageway at the side.  As he studied the situation he kept moving to avoid observation, and presently, at a moment when he was quite alone in the street, walked rapidly to the house Chauvenet had entered.

Gentlemen in search of adventures do well to avoid the continental wall.  Mr. Armitage brushed the glass from the top with his hat.  It jingled softly within under cover of the rain-drip.  The plaster had crumbled from the bricks in spots, giving a foot its opportunity, and Mr. Armitage drew himself to the top and dropped within.  The front door and windows stared at him blankly, and he committed his fortunes to the bricked passageway.  The rain was now coming down in earnest, and at the rear of the house water had begun to drip noisily into an iron spout.  The electric lights from neighboring streets made a kind of twilight even in the darkened court, and Armitage threaded his way among a network of clothes-lines to the rear wall and viewed the premises.  He knew his Geneva from many previous visits; the quarter was undeniably respectable; and there is, to be sure, no reason why the blinds of a house should not be carefully drawn at nightfall at the pleasure of the occupants.  The whole lower floor seemed utterly deserted; only at one point on the third floor was there any sign of light, and this the merest hint.

The increasing fall of rain did not encourage loitering in the wet courtyard, where the downspout now rattled dolorously, and Armitage crossed the court and further assured himself that the lower floor was dark and silent.  Balconies were bracketed against the wall at the second and third stories, and the slight iron ladder leading thither terminated a foot above his head.  John Armitage was fully aware that his position, if discovered, was, to say the least, untenable; but he was secure from observation by police, and he assumed that the occupants of the house were probably too deeply engrossed with their affairs to waste much time on what might happen without.  Armitage sprang up and caught the lowest round of the ladder, and in a moment his tall figure was a dark blur against the wall as he crept warily upward.  The rear rooms of the second story were as dark and quiet as those below.  Armitage continued to the third story, where a door, as well as several windows, gave upon the balcony; and he found that it was from a broken corner of the door shade that a sharp blade of light cut the dark.  All continued quiet below; he heard the traffic of the neighboring thoroughfares quite distinctly; and from a kitchen near by came the rough clatter of dishwashing to the accompaniment of a quarrel in German between the maids.  For the moment he felt secure, and bent down close to the door and listened.
