Zion Sawyer is about to marry the man of her dreams. Her focus has narrowed to planning her wedding and running her coffee shop, but when Condor asks her to meet with him, she isn’t prepared for what the Rusty Bucket’s leader wants. Fellow motorcycle gang member Hatchet Henry reveals that he was part of a 1970s bank robbery, which resulted in the death of a security guard. His accomplice, Whistling Willie, has always sworn he didn’t kill the guard, but he’s serving a life sentence at Corcoran for the crime. Now Willie is dying, and he wants one last taste of freedom. Condor asks Zion to help prove Willie innocent. Does the Redheaded Sleuth have one more criminal investigation in her, or will she decide to honor Tate’s wishes and never take on another case again
