在这部探案新窍门 第十二季剧情/喜剧/犯罪片中,Gerry is spooked by the discovery of UCOS's latest victim: his old DCI, whose body has lain untouched under a basement for 30 years. As deep-rooted accusations of police corruption and underhand dealings begin to surface, Gerry has to face up to some skeletons in his own closet, and it's a race against time for the team to help before his murky past catches up with him. While he's supposed to be babysitting his grandson, Gerry is convinced only he holds the key to the investigation and leaves the team quite literally holding the baby as he goes Awol in a bid to uncover the truth.
Gerry is personally involved when the body of Martin Ackroyd, his first inspector when he joined CID, is discovered having been missing for thirty years. Prime suspects are former officers Bryant and McCabe, whom Ackroyd believed to be corrupt and are now involved with career criminal Dominic Chapman, as is Ackroyd's ex-superior Ronald Sainsbury who colludes with them to discredit Gerry. Gerry tracks down Tommy Naylor, another crook the dead man had in his sights and whom Bryant and McCabe unsuccessfully attempted to frame. Gerry decides to take the law into his own hands after his daughter Caitlin is threatened but this only makes him seem guilty of the murder in Sasha's eyes.
