Alex Cross Must Die is the 32nd installment in James Patterson's bestselling Alex Cross thriller series, published by Little, Brown and Company (a Hachette Book Group imprint) in November 2023.

Detective Alex Cross is thrust into one of his most personal and dangerous cases yet. A cunning serial killer known as the Dead Hours Killer is targeting airline pilots, and when a commercial jet is shot down at Reagan National Airport using a stolen Vietnam War-era machine gun, Cross and his partner John Sampson are called in to stop the carnage. As they close in on the killer, Cross discovers he himself is on the target list — and must race to stop a murderer before becoming the next victim.
