All looks set fair for Major Matthew Hervey: news of a handsome legacy should allow him to purchase command of his beloved regiment, the 6th Light Dragoons. He is resolved to marry, and rather to his surprise, the object of his affections — the widow of the late Sir Ivo Lankester — has readily consented. But he has reckoned without the opportunism of a fellow officer with ready cash to hand; and before too long, he is on the lookout for a new posting. However, Hervey has always been well-served by old and loyal friends, and Eyre Somervile comes to his aid with the means of promotion: there is need of a man to help reorganize the local forces at the Cape Colony, and in particular to form a new body of horse.
