Inhalt: Just two weeks to go before the Cherringham Charity Christmas Concert. Choir rehearsals are in full swing. Then the worst thing happens: Kirsty Kimball, one of the singers, is found dead from a severe allergic reaction to one of the home-made rehearsal cakes. Jack is pulled in to help bolster the depleted choir, and soon he's convinced that Kirsty's death was no accident. Sarah agrees, and quickly the two of them are immersed in the jealousies, rivalries and passions of Cherringham's Rotary Club choir.
