When Sela Lamont opens her first official art show, she gets more than she bargained for. Not only is her heirloom locket ripped from her neck, then recovered by the sudden appearance of her quasi-boyfriend Jimmy, a cavalier MI5 agent, but they find cryptic information within it, leading them to discover a multi-national plot.

With an ongoing penchant for blundering into the unknown, and with Jimmy away on a mysterious assignment, Sela finds herself the focus of an unscrupulous gang, intent on retrieving the locket. She is forced into a game of cat and mouse with one of the gang members, and, acting on survival instinct alone, she throws caution to the wind, ending up in the very epicentre of the plot.
