I accompanied them. My purpose in Mayfair that afternoon had been an appointment with the wife of my former commander, at their Brook Street house, but I was just as happy to climb into the cart and let it take me in the opposite direction.

Louisa would be annoyed when I sent my regrets, but I welcomed the chance to avoid the meeting. I had a feeling I knew what she wanted to speak to me about, and I wanted nothing to do with it. Also, her husband might be home, the man who had once been my mentor and closer to me than a brother. That same man had ended my career and very nearly my life.

The drover made his slow way through the traffic, still bottled, to Swallow Street, a narrow artery south. Plans were underway to widen this street into an elegant thoroughfare so that the Prince Regent would be able to travel a more or less direct route from a park that would be built north of Oxford Street to his opulent Carleton House just below Pall Mall. There the Prince, who'd been Regent for five years now, dwelled in splendor, while his father, King George, slowly lived through his madness in his padded rooms in Windsor. The rest of us used Swallow Street simply to leave graceful Mayfair for the darker regions of London.

The fog lowered. By the time we reached Haymarket, the rain had ceased, but the blanket of mist enveloped us. I held the man steadily against the bumps of the cobbles and the sway of the wagon. His wife simply sat, staring at nothing. Farther south, in Charing Cross, a street puppet theater had attracted a fair number of watchers, who, despite the darkening, chill weather, cheered or booed with enthusiasm.

The drover turned his cart into a small lane that opened from the Strand. The lane was narrow and dark, rather like the one in which I had lodgings, but the tall houses crowded here were painfully neat and respectable. The drover found the house and stopped his wagon before it.
