A grey, sunless morning on the Firth of Tay. Across a wide, sandy waste stretching away to the misty sea at Budden, four men were walking. Two wore uniform-one an alert, grey-haired general, sharp and brusque in manner, with many war ribbons across his tunic; the other a tall, thin-faced staff captain, who wore the tartan of the Gordon Highlanders. With them were two civilians, both in rough shooting-jackets and breeches, one about forty-five, the other a few years his junior.
