Superintendent P. Marlow was a corrupt police officer who gets involved with criminal Fraser Black. Fraser gets him on side. He returns in 2014 and in April, Fraser forces Ste Hay to take the blame for crashing into Sinead O'Connor's car and killing a policeman DS Sykes. However, it transpires that Fraser is the culprit and Ste begs Marlow to tell Fraser that it wasn't his fault that this information came out. Sam Lomax and Sonny Valentine overhear and he gets fired from his police job. He is later murdered by Fraser.
