A killer with a sweet tooth keeps leaving candy wrappers at crime scenes, which, in any other case, might have been the oddest detail about it. However, as Chloe Decker looks further, the cases become stranger and stranger. Monkeys killing a man in a locked laboratory? A body appearing without a trace on a busy LA sidewalk? A car appearing out of thin air? Either this killer has serious skill, or there's something more powerful at work here. Warning: Gabriel has a potty mouth.
