When local resident Irene Symonds is found murdered in a method matching that of the 'The Good Samaritan' killer, Sister Boniface fears the worst - the killer is back. Also Sam Gillespie is told to come off the case as he had apparently convicted the wrong number. However, Sister is soon on the case, riding her Vespa and catching the killer.
This is a complicated episode and a little convoluted and not so exciting as the others, however it still a fun watch as most episodes are, thanks to the characters and the light touch. Can't wait for the Christmas episode as mentioned at the end. In these days of glum TV dramas it's nice to watch a program like this.
