The horses clip-clopped through the darkened square at a good rate, but not so fast that he couldn’t make out the row of bog-houses—or the vague figures that surrounded them, dim as the moths that flitted through his mother’s garden at nightfall, drawn by the perfume of the flowers. He drew a deep, deliberate breath through the open window. Quite a different perfume reached him from the bog-houses, acrid and sour, and under it the remembered smell of the sweat of panic and desire—no less compelling in its way than the scent of nicotiana to the moths.

The bog-houses of Lincoln’s Inn were notorious; even more so than Blackfriars Bridge, or the shadowed recesses of the arcades at the Royal Exchange.

A little distance farther on, he rapped on the ceiling with his stick, and the carriage drew to a halt. He paid the driver and stood waiting until the carriage had quite disappeared before turning into Barbican Street.

Barbican Street was a curving lane, less than a quarter mile long, and interrupted by the passage through it of the Fleet Ditch. Covered over for part of its length, the remnants of the river were still open here, spanned by a narrow bridge. The street was various, one end of it a mix of tradesmen’s shops and noisy taverns, these yielding place gradually to the houses of minor City merchants, and terminating abruptly beyond the bridge in a small crescent of large houses that turned their backs upon the street, facing superciliously inward to a small private park. One of these was Lavender House.

Grey could as easily have arrived at the crescent by carriage, but he had wanted to begin at the far end of Barbican Street, approaching his goal more slowly afoot. The journey would give him time to prepare—or so he hoped.

It had been nearly five years since he had last set foot in Barbican Street, and he had changed a great deal in the interim. Had the character of the neighborhood altered as well?

It had not, judging by his first impressions. The street was a dark one, lit only by random spills of window-light and the wash of a cloudy half-moon, but it bustled with life, at least at the near end of the street, where numerous taverns insured traffic. People—mostly men—strolled up and down, brushing shoulders and shouting greetings to friends, or lounged in small gangs around the entrances to the public houses. The smell of ale rose sweet and pungent on the air, mixed with the scents of smoke, roast meat—and bodies, hot with drink and the sweat of a day’s labor.
