Headon Hill,  The Duke Decides (1904)

“ Moved by a sudden impulse, Forsyth went into the bedroom, shutting the door behind him so as to be in the dark. The window commanded a view of the street, and the blind had not been drawn. Looking down, he saw a man sauntering on the opposite pavement, who presently coming under the rays of a streetlamp was revealed as Marker. Forsyth waited until the spy turned and slowly retraced his steps, and then went back into the sitting-room.
“You have convinced me that there is something in all this,” he said. “That fellow is mouching about outside.”

Headon Hill,  The Duke Decides

“ Open violence at any rate was not to be apprehended from the stunted little figure of a man who coweringly obeyed his order.
But as his captive turned round and showed his sullen face the Duke knew that this was no mere impecunious vagabond, sneaking a cheap railway journey. His fellow passenger was part and parcel of the peril that menaced him—had, in fact, been a fellow-passenger of his before. For the wizened, mean-looking face was the face of the spy Marker, who had been pointed out to him by Leonie on board the St. Paul, and who had afterwards shadowed him to the Hotel Cecil on landing.
