Comedian and serial killer Dylan Miles had a co-conspirator of sorts, his ventriloquism figure. Miles has a new goal that Bex and team try to piece together before more blood is shed.

Bex and the team must hunt down escaped inmate Xander Wax, a killer with a knack for poisoning through unpredictable methods. Things back at the Command Center come to a head, pushing the team further than they've ever been before.
