About K.C. Constantine

K. C. Constantine (a pseudonym for Carl Constantine Kosak; born 1934 in McKees Rocks, Pennsylvania) is an American mystery author.

Little is known about Kosak, as he prefers anonymity and has given only a few interviews. He was born in 1934 and served in the Marines in the early 1950s. He lives in Greensburg, Pennsylvania with wife Linda.

He is an alumnus of Westminster College in New Wilmington, Pennsylvania and claims that he "flunked freshman composition twice" because he "did not know how to make an English sentence." (As reported in the bulletin of that college's "Friends of the Library" Autumn, 1990.)

Other than that, information is sketchy. He may have been a minor league baseball player (some had even been suggesting that Kosak was a pseudonym for former Major League baseball player Phil Rizzuto) and he may have studied at the University of Iowa's writers' program in the 1960s. Other evidence suggests he never got near a baseball and instead was a journalist at a western Pennsylvania newspaper.
