The Killer in the Choir 

At her husband’s funeral, Heather Mallet is publicly accused of his murder. But did she really kill her husband, as many residents of the sleepy coastal town of Fethering believe? To get to the heart of the matter, local amateur sleuths Carole and Jude join the community choir and discover that amidst the clashing egos and petty resentments there lurk some decidedly false notes. At least one chorister would appear to be hiding a deadly secret – and it’s up to Carole and Jude to unearth the truth.
