His master dressed quickly and went alone to the club for a late dinner. Most of his friends were away shooting, therefore he idled alone for an hour over the paper and then returned to his chambers.

Next morning he scribbled a hasty note to Mr Statham, making an excuse for his sudden absence, and directly after ten was seated in the Scotch express travelling out of London.

At eight that evening he stepped out upon the big, dark station at Perth, sent a telegram to the Crown Inn at Kilmaronock village for a “machine,” as a fly is called, and then took the slow branch line that runs by Crieff and skirts Loch Earn to the head of Glen Ogle, where lay the old castle and fine shooting of which Max Barclay was possessor.

A drive of three miles on the road beside Loch Voil brought him to the lodge-gates, and then another mile up through the park he came to the great portico of the castle.

It was nearly midnight. Lights were still in the billiard-room of the fine old castellated mansion, which Max’s father had modernised and rendered so comfortable, and when Charlie rang, Burton, the butler, could not suppress an exclamation of surprise.

In a few moments, however, Charlie burst into the room where Max and five other men were playing “snooker” before retiring.

The host’s surprise was great, but the visitor received a hearty welcome, and an hour later, when the guests had gone to their rooms, the two friends stood alone together in the long old-fashioned drawing-room which, without a woman’s artistic hand to keep things in order, was rapidly going to decay.

A big wood fire blazed cheerfully in the wide old-fashioned grate, for October evenings in the Highlands are damp and chill, and as the two men stood before it they looked at one another, both hesitating to speak.

Across Charlie’s mind flashed those suspicions which had oppressed him in Belgrade. Was the man before him his enemy or his friend?

“Well,” he blurted forth, “I’ve come straight up to see you, Max. I only arrived home last night. I want to see you concerning Marion.”
