It began well enough: an uneventful half-circuit of Leicester Fields, traversing the east side of the square, then swinging round to head west along its southern edge. This ought to have been a straight shot to Hay Market; but the driver called for a turn too soon, and she felt the box revolving leftwards onto St. Martin’s. Out one window she could see a narrow burqa -view of Sir Isaac Newton’s house; out the opposite, a flare of light where none ought to be. Someone had lit a bonfire in the southwestern corner of Leicester Fields, blocking the outlet to Hay Market. And they’d done it in the last minute or so, for Eliza had scanned the square carefully before suffering herself to be boxed, and seen nothing.
