But what will his discovery mean for Faye and Emma?
In the salon flat, Craig is bored and as he watches the street through a set of binoculars from the window, he's shocked by what he sees.
Later, Faye's heart sinks after Craig strikes a £20 wager with Tyrone that he’s going to find the original owner of the wooden crutch and both Faye and Emma despair when he reveals that he has sent the crutch to the lab to have it tested for fingerprints.
When Craig later tells Roy about the crutch, with the initials THS, and how he’s trying to trace the owner, Roy reckons the crutch might belong to Trafford Health Services.
Back in the salon flat, Craig is elated as he taps away on his laptop and Emma masks her panic when he reveals the crutch belongs to Trafford Health Services.
