Christine looked at the watch on her wrist and saw that it was past eleven.

"Oh, I should think so, Mr. Saxby. The closing of all the shutters is usually a sign that she is up and about."

It is, in fact, a practice in all Karoo houses to close every window and shutter at about ten o'clock each morning, not throwing them open again until sunset. This keeps the interiors extraordinarily cool, and, as the walls are usually whitewashed, there is plenty of light.

"I expect I shall find her in the drawing-room," Saxby remarked, and passed on. Christine saw him leave again about half an hour later. Then the sound of waltz-music within the closed house told that Mrs. van Cannan was beguiling away the rest of the long, hot morning in a favourite fashion. At noon, the heat, as usual, made the summer-house untenable, and its occupants were driven indoors.

Lunch introduced the only excitement the quiet monotony of the day ever offered, when the men came filing into the soft gloom of the dining-room, bringing with them a suggestion of a world of work that still went on its way, come rain, come shine. All of them took advantage of the custom of the climate to appear coatless. Indeed, the fashion of shirts was sometimes so décolletée as to be slightly embarrassing to English eyes. Only Saltire paid the company the compliment of unrolling his sleeves, buttoning the top button of his shirt, and assuming a tie for the occasion.

Everyone seemed of opinion that the summer rains were brewing and that was the reason of the insufferable heat.

"We'll have a couple of days of this," prophesied Andrew McNeil, "then down it will come with a vengeance."

"The land wants it, of course, but it will be a confounded nuisance to me," remarked the forestry expert.

"Oh, Mr. Saltire, you are insatiable in your work of murder," smiled his hostess. "Are you as merciless in all your dealings?" She looked at him with provoking eyes. Christine hardened herself to hear an answer in the same vein, but was as agreeably relieved as surprised.

"I want to get the work done," said Saltire briefly.
