Rozan, S. J. Lydia Chin/Bill Smith novels.

"The Most Southern Place on Earth: that's what they call the Mississippi Delta. It's not a place Lydia Chin, an American-born Chinese private detective from Chinatown, NYC, ever thought she'd have reason to go. But when her mother tells her a cousin Lydia didn't know she had is in jail in Clarksdale, Mississippi - and that Lydia has to rush down south and get him out - Lydia finds herself rolling down Highway 61 with Bill Smith, her partner, behind the wheel. From the river levees to the refinement of Oxford, from old cotton gins to new computer scams, Lydia soon finds that nothing in Mississippi is as she expected it to be. Including her cousin's legal troubles - or possibly even his innocence. Can she uncover the truth in a place more foreign to her than any she's ever seen?"--Publisher description
