Former investment banker Johan Golding -- Joe -- is the newest member of the Hartley and Edwards Investigations team. He's thrilled to be shadowing Kitt Hartley and her right-hand woman Grace Edwards, soon adjusting to the low-level madness of the Hartley and Edwards offices. But Joe is thrown in at the deep end when a man known as Ralph Holmes goes missing. Police refuse to investigate, as his disappearance seems voluntary, but his niece, Carly, is determined to discover the truth. As the team begin to investigate, they deduce there's more to this disappearance than meets the eye. Drawn into a web of international conspiracies and possible murder, they must determine who Ralph Holmes really was - and who he was working for. In their most dangerous case yet, the team are in a race against time to uncover the truth, before anyone else gets hurt.
