Wedding bells are chiming in the idyllic, coastal town of Stonebridge. For Sam and Emily, it should be the happiest day of their lives. But, on the morning of the ceremony, the best man is found dead. The police quickly write his death off as a tragic accident, but something doesn't seem right to wedding guest and groomsman, Adam Whyte. Armed with an encyclopaedic, but ultimately ridiculous knowledge of television detective shows and an unwarranted confidence in his own abilities, Adam and his best friend (and willing Watson) Colin, set out to uncover what actually happened to Daniel Costello.
