Detective Kreps (Michael Rapaport) has been a thorn in our trio's side all season. But until episode eight, it just seemed like he was a standard, run-of-the-mill creepy cop. After the blackout, Mabel realises he has glitter stuck to the back of his neck — meaning he was the person who took the matchbook and ran off.
After his conversation with Mabel at the boxing gym, it seems Kreps thinks he and Cinda are in love, and Mabel is able to figure out that they met while Cinda was recording "All Is Not OK in Oklahoma." Viewers learn that he helped hide evidence in Oklahoma to make the podcast better. But in the finale episode, viewers learn this was a fake out — Kreps fell in love with Poppy and helped her carry out the murder.
Our verdict: Guilty
