The Woman Who Found Grace — B. Reece Johnson

Grace "Killer" Frost, a gorgeous and seemingly ageless platinum blonde, has spent the last 30 years in a mental institution for chopping up two of her women friends and shipping them off in a steamer trunk. Now she is released back into society -- and unexpectedly into the arms of international artist-turned-sleuth Cordelia Morgan, whose own shadowy past is closing in on her. This is the third novel in the acclaimed Cordelia Morgan mystery series.
