And it seems that even his neighbours aren't safe from his new wicked ways when he targets an unsuspecting Ryan.
The former builder-turned-killer takes out a wad of Rick's cash next week and hides it in a desk draw before heading out to do some more dodgy business, leaving Ryan to mind the furniture shop.
But he soon regrets leaving Ryan in charge when he returns back to the shop and finds Ryan has sold the desk - complete with the stash of cash still hidden in the draw.
Ryan's proud of himself for selling the furniture for £200... but the smile is soon wiped off his face when a fuming Gary reveals there was £650 hidden in there!
Ryan apologises for apparently not realising his mistake, and tells Gary that the desk was bought by Mary, who wanted it for the flower shop.
But when Gary calls at the florist to see if he can get his cash back, he's annoyed to find it is gone.
Even Mary claims she hasn't seen the cash and swears blind that the draws were empty when she bought the furniture.
However, it seems Ryan might know more about Gary's missing money than he is letting on, because he's soon telling Alya all about how he has just come into some money, claiming that he has sold some of his old vinyls.
Alya is thrilled when Ryan tells her he can now afford to join her in Copenhagen, but its not long before Gary gets wind of Ryan's new-found wealth and works out where his money went.
Gary confronts Ryan over his deceit and threatens to call the police - meaning it looks like Ryan's city break might be off the cards once again.
Eventually Ryan admits that he is the one who took the cash, but claims that he didn't realise it belonged to Gary when he took it.
But Gary soon turns nasty and tells him that he can pay back every penny, except this time he will be playing it back with interest too.
With Ryan now in debt to Gary, is he about to find himself in the killer's bad books if he fails to pay the money back?
Ryan has no idea just how dangerous Gary can be... has he just inadvertently signed his own death warrant?
Coronation Street airs on Mondays, Wednesdays and Fridays at 7.30pm and 8.30pm on ITV.
