S16·E50 No Man's Land

Cryer decides to take it upon himself to discover the identity of a body found on a roundabout, after Webb shows a less than caring attitude towards the case. His investigation leads him to believe that the deceased is Graham Dennis Anderson, a man wanted by the fraud squad for falsely selling pensions and other financial services to customers. Cryer is convinced that Anderson's business partner is in fact his alter-ego, who created Anderson as a way of escaping capture. However, his trail soon leads him to uncover one individual with several alter-egos – and as pieces of the what seems impossibly difficult jigsaw begin to piece together, he finds himself with a body it seems nobody can identify.
