It's Cait and Bud's wedding weekend and for the first time she feels like a bride - or at least, she's supposed to. But then the rain won't quit, the supposedly romantic Welsh castle feels creepy, and there's a dead body on the stairs. What first appears to have been the untimely, unfortunate, and accidental death of their wedding choirmaster quickly reveals itself to have been a murder. When a series of mysterious events occur around the castle, Cait, Bud, and Cait's sister Sian tackle the case of The Corpse with the Sapphire Eyes, attempting to solve the mystery before another sinister event can ruin their destination wedding. 2014.
