Believing there to be a connection between the murder and the ongoing thefts, Judith employs the help of volunteers from the archaeological dig as well as Becks and Suzie to enact a plan to catch the thieves red-handed. Suzie inadvertently reveals too much about the case and puts herself in danger – will the women be able to catch the killer and save Suzie before it’s too late?
