At 3 p.m. on the 13th February, a huge army of soldiers swept into the remote Highland Valley of Glencoe, a stronghold of the MacDonald clan. The Master of the Stair sent them there. Cruel and ambitious, he did not shrink from mass murder to satisfy his lust for power. Jock Campbell led them. At last his chance had come to rid Scotland of his old enemies and reign supreme in the Highlands. Delia tried to stop them.

A beautiful Jacobite spy, she risked her life to warn the MacDonalds and save the man she loved. Fighting against time and the evil madness or her opponents, Delia plotted secretly to avert the threatened tragedy.
