Malcolm and Simone's relationship is moving at a rapid pace. They are engaged and undergoing IVF treatment for a child.
Malcolm is now treasurer of an angling club, but is secretly embezzling funds. When this is reported to DS Charlie Henry (John Hannah), he raids their home and finds stolen laptops and an unlicensed firearm. Malcolm is pulled in for questioning, but Charlie's frustrations continue to grow when legal technicalities result in Malcolm being cleared of the embezzlement, theft and firearms offences.
