Ralph McInerny, of the Father Dowling mysteries.
I did not like this book. If I did not need it for my challenge I would not have finished it. I was bored and could not get into the story. I felt like things were repeated unnecessarily and clues were left out.
Description from Booklist on amazon:
Wily octogenarian Sister Mary Teresa continues to dispense sensible
advice and unravel mysteries with scholarly precision. While struggling
to breathe new life into the moribund Order of Martha and Mary, Sister
Mary Teresa also finds time to assist Lieutenant Richard Moriarity of
the Chicago Police Department in solving a gruesome series of homicides
perpetrated by a vicious stalker. Without ever leaving the comfortable
confines of her Walton Street convent, she manages to link the
unfortunate victims to a long-defunct classics club that included
several of her former pupils as members. A cleverly crafted caper that
reaches back in time to unveil a festering motive for murder.
Entertaining fare for armchair detectives. Margaret Flanagan
