Yellow backed adventure novels by Conan Doyle and Clifford Ashdown shouldered worn calf saints' lives, antiquated chemistry texts, Carlyle, Gibbon, de Sade, Balzac, cheap modern reprints of Aeschylus and Plato, Galsworthy, Wilde, Shaw. In front of the bone clean fireplace, a massive oak chest, strapped with leather and the only furniture in the room, held a cheap American oil lamp of clear glass and steel, the trimmed wick in about half a reservoir of oil. Lydia produced a match from her pocket, lit the lamp, and by its uncertain light read the titles of the several new volumes, half unwrapped from their parcel paper, which lay beside it. A French mathematics text. A German physics book by a man named Einstein. The Wind in the Willows. How much time left?

With a certain amount of difficulty Lydia produced from beneath her coat a curious device-a simple brass bug sprayer of the pump variety, its nozzle carefully capped with a pinch of sticking plaster-and a shoulder sling manufactured from a couple of scarves in last year's colors. She removed the cap, reslung the sprayer on the outside of her coat and, picking up the lamp, moved off through the house.

The first-floor room contained more books. The rear chamber, book lined also, held furniture as well. A heavy table, strewn with mathematics texts, abaci, astrolabes, armillary spheres, a German Brunsviga tabulation machine, and what Lydia recognized dimly as an old set of ivory calculating bones. At the far end of the room loomed a machine the size of an upright piano, sinister with glass, metal, and ranks of what looked like clock faces, whose use Lydia could not begin to guess. Near it stood a blackwood cabinet desk, German and ruinously old, carved thick with gods and trees, among which peeped the tarnished brass locks to concealed recesses and drawers.

A wing chair of purple velvet, very worn and rubbed, stood before a fireplace whose blue and yellow tiles were smoked almost to obscurity, its arms covered with cat hair, an American newspaper lying on its seat. Movement caught her eye and made her gasp, but it was only her own reflection in a yellowed mirror, the glass nearly covered by a great shawl of eighteenth-century black point lace that hung over its divided pane.
