The Big Empty (Elvis Cole and Joe Pike Series #20)

Private investigator Elvis Cole and his enigmatic partner, Joe Pike, face a cryptic case and a terrifying, unpredictable killer in this twisty, satisfying thriller from #1 New York Times bestselling author Robert Crais.

Traci Beller was thirteen when her father disappeared in the sleepy town of Rancha, not far from Los Angeles. The evidence says Tommy Beller abandoned his family, but Traci never believed it. The police couldn't find her dad and neither could the detectives her mother hired, but now, ten years later, Traci is a super-popular influencer with millions of followers and the money to hire a new detective: Elvis Cole.
    Taking on a ten-years-cold missing person case is almost always a loser, but Elvis heads to Rancha where he learns an ex-con named Sadie Givens and her daughter, Anya, might have a line on the missing man.  But when Elvis finds himself shadowed by a deadly gang of vicious criminals, the simple missing persons case becomes far more sinister and dangerous. Elvis calls in his ex-Marine friend, Joe Pike, to help, but even Pike might not be able to help.
    As Elvis Cole and Joe Pike follow Tommy Beller's trail into the twisted, nightmare depths of a monstrous evil, the case flips on its head.  Victims become predators, predators become pray, and when everyone is a victim, can Elvis Cole save them all? 
    In a case that tests Elvis Cole's loyalty to his clients and himself, the truth must come out no matter the cost. Elvis must face The Big Empty and see justice done.
