At first glance, Jellicoe Close seems to be a perfect suburban street -- well-kept houses with pristine lawns, neighbours chatting over garden fences, children playing together. But there are dark secrets behind the neat front doors, hidden dangers that include a ruthless criminal who will stop at nothing. It's up to DS Maeve Kerrigan and DI Josh Derwent to uncover the truth. Posing as a couple, they move into the Close, blurring the lines between professional and personal as never before. And while Maeve and Josh try to gather the evidence they need, they have no idea of the danger they face -- because someone in Jellicoe Close has murder on their mind.
