Where's Charlie?
In season three Charlie and Blake were always sleuthing together. In season four he hardly seems to appear at all even as a boarder at Lucien's. I miss him. Blake is now either with Sgt Hobart or Supt Frank Carlyle. Maybe because Carlyle (unlike Munro) seems to welcome Blake's "interference" the writers have decided to sideline Charlie, but I don't know why they would feature Hobart more since he is less colorful than Charlie.
I am four episodes in now. Maybe he will show up more later.
