Temple Barr and Midnight Louie are up to their tails in froufrou, chapeaux, and murder when the Red Hat Sisterhood convention hits Las Vegas. Electra Lark, Temple's spirited landlady, has dragged her to the con. Accused of murder after a woman is found strangled with an official Red Hat Sisterhood scarf, Electra begs Temple to clear her name by posing as a pink-hatter, an under-fifty member of the organization.
Louie and his partner in Midnight Investigations Inc., Midnight Louise, join the hunt for the killer at the Crystal Phoenix. They find old friends already there, including C-movie actress Savannah Ashleigh, and her Persian cats, Louie's ex-love, the Divine Yvette, and her sister Solange.
As Temple and Louie dig under all the makeup and shopping bags it becomes clear that a whole lot of folks want to crush or cash in on the red-hot rage of female empowerment that is the Red Hat Sisterhood.
