"You're paid to act, not think; do you understand?" he said in a husky, suppressed voice; but his long fingers were twitching.

"I understand," said Kyte.

Sprowl's lean head jerked; Kyte went; and the master of the house strode back into the library and resumed his pacing.

Boots, spurs, the skirts of his riding coat, even his stock were stained with mud and lather; and there was a spot or two across his sun-tanned cheeks.

Presently he walked to the bay-window which commanded part of the west veranda, and looking out through the lace curtains saw Ledwith sitting there, his sunken eyes fixed on the westering sun.

The man's clothing hung loosely on his frame, showing bony angles at elbow and knee. Burrs and black swamp-mud stuck to his knickerbockers and golf-stockings; he sat very still save for a constant twitching of the muscles.

The necessity for nervous and physical fatigue drove Sprowl back into the library to tramp up and down over the soft old Saraband rugs, up and down, to and fro, and across sometimes, ranging the four walls with the dull, aimless energy of a creature which long caging is rendering mentally unsound.

Then the monotony of the exercise began to irritate instead of allaying his restlessness; he went to the bay-window again, saw Ledwith still sitting there, stared at him with a ferocity almost expressionless, and strode out into the great hallway and through the servant-watched doors to the veranda.

Ledwith looked up, rose. "How are you, Langly?" he said.

Sprowl nodded, staring him insolently in the face.
