THE DEVIL YOU KNOW 10:00 p.m. on Viceland. For fans of true crime, the premiere of this five-episode documentary series provides ample opportunity to delve into an unsolved and disturbing murder case. Set in a rural community outside of Winston-Salem, N.C., the show centers on John Lawson, a self-proclaimed Satanist who renamed himself Pazuzu Algarad. When the bodies of two missing men are found in his basement, Algarad’s ties to Satanism and continuous run-ins with the law seem to build up a case against him — but the reality of what happened to the men may not be what it seems. The series follows Chad Nance, a local journalist, as well as the neighbors, authorities and friends — some of whom are self-styled Satanists themselves — who have tried to unravel the mysterious case.
