When the head of a local book club is robbed and battered to death with her walking stick, suspicion soon falls on club members. When the club is exposed as a front for a lucrative investment portfolio, many believe that money and riches were the motive behind the brutal attack. The investigation becomes increasingly urgent as more book club members are killed. As the hidden secrets and mysterious pasts of these women are uncovered, Barnaby finds that for one murder, unrequited love is a stronger motive than money.
