They took little or no account of the immediate consequences of their act, and a man like Milburgh, in his desperation, might in his very frenzy overlook the possibility of his crime coming to light through the very deed he had committed to cover himself up.
He had reached the bottom of Edgware Road and was turning the corner of the street, looking across to the Marble Arch, when he heard a voice hail him and turning, saw a cab breaking violently to the edge of the pavement.

Whiteside listened in silence.
"There may be something on that side," he said at last when Tarling had finished.
