It's the following Thursday. Elizabeth has received a letter from an old
colleague, a man with whom she has a long history. He's made a big mistake, and
he needs her help. His story involves stolen diamonds, a violent mobster, and a
very real threat to his life. As bodies start piling up, Elizabeth enlists
Joyce, Ibrahim and Ron in the hunt for a ruthless murderer. And if they find the
diamonds too? Well, wouldn't that be a bonus? But this time they are up against
an enemy who wouldn't bat an eyelid at knocking off four septuagenarians. Can
the Thursday Murder Club find the killer (and the diamonds) before the killer
finds them?
