Big Red Tequila (ISBN 9780553576443, 1997) is the first novel in Rick Riordan's prizewinning Tres Navarre series. It is a fast-paced crime story about an unusually talented and flawed hero, Jackson "Tres" Navarre, a third generation Texan. Tres has a PhD from Berkeley in Medieval Studies and English, works as an unlicensed private eye, and is a t'ai chi master.
After ten years in the San Francisco Bay area, Tres Navarre returns home to San Antonio, Texas to investigate the unsolved murder of his father, Bexar County sheriff Jackson Navarre, and to rekindle a romance with his high school sweetheart, local art gallery owner Lillian Cambridge. The more Tres looks into the unsolved crime, the more trouble comes his way.
This novel won the Anthony Award for best original paperback and the Shamus Award for best First P.I. novel in 1997.[1]
