No Witnesses by Nancy Sanra

This cliff-hanger of a mystery set in San Francisco, introduces Detective Tally McGinnis, the brains and brawn behind the Phoenix Detective Agency. But Tally is no great sleuth at protecting her own heart. And so, when her ex-lover Pamela Tresdale is arrested for the grisly murder of a wealthy Texas heiress, Tally rushes to the rescue. Despite friends' warnings, Tally is drawn once again into Pamela's web of deception and betrayal, as she attempts to clear her and find the real killer.

Memorable characters, crisp dialogue, and non-stop action make this a gripping whodunit. Look for the sequel.
