Show of the week: Turn

Those nasty Brits. Long before they won us over with a succession of mop-tops, boy wizards, and costume dramas, they were boarding troops in our homes and running around like they owned the place. This suspenseful new series draws from the true history of America’s first spy unit, the Culper Ring, to tell the story of how a Long Island farmer with a Tory father and rebel friends wound up delivering crucial secrets to George Washington’s army as the colonies’ fate hung in the balance. Jamie Bell stars. Sunday, April 6, at 9 p.m., AMC
