The year is 2019, and a drug used to treat soldiers for post-traumatic stress disorder, nicknamed "Lullaby," has hit the streets. Swallowing a little pill erases traumatic memories, but what happens to a criminal trial when the star witness takes a pill and can't remember the crime? When two women are murdered in quick succession, biracial police detective Hannah McCabe is charged with solving the case. In spite of the advanced technology, including a city-wide surveillance program, a third woman is soon killed, and the police begin to suspect that a serial killer is on the loose. But the third victim, a Broadway actress known as "The Red Queen," doesn't fit the pattern set by the first two murders.

With the late September heat sizzling, Detective Hannah McCabe and her colleagues on the police force have to race to find the killer in a tangled web of clues that involve Alice in Wonderland, The Wizard of Oz, and Abraham Lincoln's assassination. Fast-paced and original, this is a one-of-a-kind mystery from an extremely talented crime writer.
