With a new Police Scotland job, a new-ancient home, a loving pet, and a fresh outlook, Rory and Alex are almost ready for their marriage—as soon as bonnie Scotland can figure out how to do it. Working on the restoration of an old Jacobite tower house, they find evidence of a serious crime. But with no handy forensics lab on the wind-swept heathland, they don’t know whether it happened recently, or a hundred years ago. For his part, Alex’s new duties also mean a new identity, as he follows the trail of drugs and dirty cops. Former playboy Rory is anything but a detective. But with Alex tied up in his current job, he finds himself chasing down clues to a mystery lurking in Brash Tower itself. Their independent investigations uncover some startling secrets—and a source of immediate peril—as Brash Tower becomes once again a fortress against a brutal enemy. Will Rory and Alex ever tie that infernal knot—or will the high moor become once again a desolate reminder of what might have been?
