The Busybody Book Club by Freya Sampson

Nova works at the St. Tredock Community Center and is due to be married in a few days to her boyfriend Craig. When £10,000 that was designated for a new roof for the center is stolen, it puts Nova's job in jeopardy. Nova was the one to lock the building the previous evening after a meeting of the community book club. The book club members, Phyllis, Arthur, and teenager Ash wonder if the fifth book club member Michael was the culprit, since he left the meeting abruptly. Then Michael's mother dies suspiciously and he disappears, which leads the quartet on an amateur investigation lead by Phyllis, who has a fondness for Agatha Christie. Will the group find the murderer and uncover who took the money? The Busybody Book Club is a humorous novel of friendship similar to Clare Pooley and Jenny Colgan.
