A and B referred to two locations on the east bank of Fleet Ditch, near the prison’s northwest and southwest corners. These were marked on a survey plat, done by Hooke after the Fire. Comparing this against what he could see from his present vantage point, Daniel had now the satisfying experience of its all coming together coherently in his mind. Few human monuments were as permanent, as un-moveable, as a stone shithouse—especially one that by long-standing tradition was used by everyone in a crowded neighborhood. If Fleet Lane butcher’s boys were taking a shite at the southern end of the place in 1714, it probably meant they’d been doing so in 1614, 1514, 1414, &c. That row of privies must be among the dozen or so that had been erected over the moat. And the privy that Daniel was now looking at, next to the kitchen, must be over the moat, too—but on the opposite prong of the ox-bow. The back of that edifice was the Prison wall. Just on its other side would be a row of buildings that fronted on Fleet Lane. Some of these were slaughterhouses that, long ago, must have gathered along the north brink of that moat like flies, and employed it to carry away their offal. Likewise the prison kitchen, just there next to that privy.
