Tim O’Mara has been teaching math and special education in
the New York City public schools since 1987. He has written
several short stories, and his second Raymond Donne
mystery, Crooked Numbers (Minotaur), will hit the
bookstores October 15, 2013.

O’Mara’s top-selling debut mystery, Sacrifice Fly (Minotaur 2012),
has been nominated for the 2013 “Best First Novel”
Barry Award. The novel introduced the series hero Raymond
Donne, a Brooklyn public schoolteacher who was once an
up-and-coming police officer until a tragic accident destroyed
his knees and the future he envisioned on the force.

O’Mara was inspired to write Sacrifice Fly and create the character of
Raymond Donne after making home visits while a schoolteacher in the
poorer section of the Williamsburg neighborhood in Brooklyn. Further moved
by his many interactions with the Youth Officers of the NYPD while he served
as a middle school dean and his brother’s stories as a police sergeant,
O’Mara believed that a character with experience in both worlds would
make a great protagonist.

For the past 13 years, he has hosted and produced a bi-weekly reading
series of poetry and prose in New York’s East Village. He lives with his
family in Manhattan, where he currently teaches math, and is a proud
member of Mystery Writers of America, Crime Writers of America,
International Thriller Writers, and several teacher unions.
