No One's That Honest

Conway is astounded when an elderly man, Charles Arthur Cullen, a former police officer, turns up at the station with a suitcase containing half a million pounds, which he claims to have found on the street. Conway asks Hollis to count the money independently but he only manages to count £499,920. As Rickman counts the money again, Conway decides to do some digging, as surely no-one could be that honest. He discovers that the land on which the money was found has recently changed hands, and is now in possession of the Met. As the scam begins to show all of its true colours, Conway attempts to bargain with Cullen in order to get a deal which suits the both of them just perfectly.
