Cisco is found armed and standing over the body of a man with Down syndrome. Cisco swears the dead man was his good friend, and he didn’t hurt him, but in his earlier life, Cisco had been gang member, a brilliant and brutal killer. After he was badly beaten, brain injuries left him him―if he is to be believed―with the intellectual intelligence of a child. Madsen's search for the truth leads him through the special needs community, East LA gang life, and pits him up against the corrupt LA Sheriff’s Department. More than a police procedural, Tricky explores questions of human nature: Whether a man can change, for better or worse, and whether redemption is possible.
