n this episode, Kat and Jethro sprint headfirst into the shadows—twice.

First, they investigate the chilling legend of the Black Flash of Provincetown—a mysterious, caped figure that terrorized the streets of Cape Cod in the late 1930s. Was it a prankster in a leotard or a supernatural harbinger of doom? Why did it smell like ammonia and make jumps that defied Newtonian physics? And most importantly: who keeps giving cryptids Olympic-level track abilities?

Then, they shift into far darker territory with the haunting story of Lonnie Franklin Jr., better known as the Grim Sleeper. For decades, he preyed upon the vulnerable and voiceless in Los Angeles, slipping under the radar due to chilling indifference and systemic failure. How did one of the most prolific serial killers in U.S. history go unnoticed for so long—and what finally led to his capture?

From shadowy specters to real-life horrors, this episode explores the thin, fraying line between folklore and fear, myth and monster.
