Detective Everett Backstrom is known for usually being right. So why are his teammates questioning his latest hunch?

On Thursday's Backstrom (9/8c, Fox), Rainn Wilson's titular detective investigates an arson/homicide believed to be perpetrated by a serial firebug known as "The Green Flame." However, after only one canvass at the crime scene, Backstrom is convinced he knows who to blame.

"The firefighters are setting fires and then stealing from the houses!" Backstrom declares in the exclusive sneak peek below. Although both Gravely (Genevieve Angelson) and Niedermayer (Kristoffer Polaha) are confused by Backstrom's conclusion-jumping, the boorish detective eventually explains his history with two specific firemen he believes to be the fire-setting thieves in question.
