Poor Sid
Despite Lady Felicia being wealthy, poor Sid has to live in an old caravan on the estate. Furthermore he doesn't get his meals provided (as we find out in series 4)
I wonder if Lady Felicia even pays him? The poor bloke gets treated like a dogsbody by just about everyone and in many episodes he is physically assaulted by the murderer or ends up harmed in some other way.
In one episode recently Father Brown didn't even buy him another pint after they had solved the murder - he just tipped the remains of his own into Sid's glass.
Sid needs a girlfriend, a cottage and a decent wage.
