Somebody Knew Her, by Gil Brewer (epub/Kindle/pdf)
Carmoody looked down again at the slack and awkwardly positioned nude body of the young girl lying on the kitchen floor of No. 5, Gulf-ways Motel. Nice figure, dusty black hair in sharp contrast against the white tile floor, dark blue eyes that were half-lidded and glaring in the lamplight. Her throat was cut.
