Beth Rich Elizabeth writes fiction. Three friends in It Could Have Been Murder establish Diamond Teams, a murder adventure company that helps organisations or individuals plan every aspect of a murder, including selecting a target, all the specifics, and any backup plans—all without actually killing anyone—and then thoroughly debriefing the client. To ensure that Diamond Teams won't assist someone in killing a target, every client must successfully complete a stringent screening process. But one client eludes them after 20 years. When his project is cancelled, he demands revenge. Diamond Teams must come up with a plan to deal with the former client, but his tactic is different from what everyone had expected.
