Apropos of nothing, there is a fun, hour long television series running on one of our PBS stations. It’s called “New Tricks” and is an import from the BBC. The premise: three retired police detectives are brought back in to work on cold cases. The three men are now working for a woman. In short order, a bond is established between the four idiosyncratic and charming main characters, which is quite enjoyable to watch. Oh, and the mysteries are pretty good too! Here in southern New England, it’s broadcast Saturday nights at nine, on WGBH. It’s good fare on a cold winter night.
