P.L. Gaus is a professor of chemistry at the College of Wooster in Wooster, Ohio.

"Gaus brings a refreshing authenticity to his unusual setting and characters. There are no wisecracking gumshoes here, but instead believable characters whose faith is explored with respect....[Blood of the Prodigal is a] fine mystery debut." - Publishers Weekly; "Broken English, the second in this mystery series about Ohio's Old Order Amish, is even better than the first," - The Columbus Dispatch"
