A "Poirot" mystery on PBS is a Thursday TV pick

"Poirot: Mrs. McGinty's Dead"

Thank you, "Masterpiece Mystery," for bringing back the amazing David Suchet as Agatha Christie's fussy Belgian sleuth Hercule Poirot. Last week's story "Cat Among the Pidgeons" was great and tonight's tale, involving the death of a cleaning woman, looks intriguing. 10 p.m. on KCTS (seattletimes.com/tvlistings).
