As the inspector was not within sight, and indeed would not be until Mulligan returned to the fixed point in Achilles Avenue, the policeman decided to solace himself with a smoke. After lighting up he threw away the match. It fell almost in the middle of the road, and flamed up brightly in a pause of the wind. Although it went out with the next gust, Mulligan, in the short time, caught with his keen eye the glitter of steel. Striking another match, he searched round, and picked up a latch-key, long and slim and with scarcely projecting wards. "He'll not get to his bed this night," said Mulligan, looking towards the corner. "If I was to run after him now------" But this, he decided, was impossible. The gentleman, walking at an unusually rapid pace, would be some distance away, and also in the meantime he might have met with a hansom. Also Mulligan had to return to the fixed point, as failure to meet his superior officer would meet with a sharp reprimand. "Ah well," said the philosophic policeman, "the young gentleman will be here to-morrow night, or maybe his sister will be still up, and I can give the key to her." On the chance of securing another half-crown, Mulligan decided that this latter course would be the more diplomatic. Astutely adopting it, he walked smartly to Achilles Avenue. A consultation of his Waterbury watch assured him that he had nearly twenty minutes to spare before the arrival of the inspector. He therefore sought out Ajax Villa, being guided thereto by the fact that the light was still burning on the first floor. But he heard no singing. However, the light showed that the lady was still in the room, though doubtless the servants--as was shown plainly by the stranger's conversation--were in bed. Mulligan walked up to the door and rang. With some foresight he argued the lady would come herself to the door, whereby he would be more certain of his money. The wind was dying down, now that it was close upon midnight, and everything in the house and garden was absolutely still. Walking up the path under the umbrageous shelter of the elms, Mulligan saw the colours of the flowers in neutral tints under a faint starry sky. There was no moon, but a kind of luminous twilight pervaded the atmosphere. Mulligan, being a Celt, was not impervious to the charm of the place which might have been Juliet's garden, so strangely had the magic of night transmuted its commonplace into romance. But his housemaid was expensive, and he hurried to the door, anxious to obtain a reward for the return of the key.
