When Priscilla Halburton-Smythe brings her London playwright fiance home to Lochdubh, the whole town is delighted -- save perhaps for love-smitten bobby Hamish Macbeth. But the morning after a posh engagement party, one of the guests, Captain Bartlett, is murdered on a grouse hunt.

Unfortunately, the prime suspects are the party guests. And a second murder soon follows the first. Now Hamish Macbeth must cut through the alibis before the killer strikes again...all the while trying to woo the lovely Priscilla from her jealous boyfriend.
