Put on your sleuthing hats, Blindspot fans. Jane Doe has a new clue, and viewers can take a crack at it before the FBI brain trust returns on Monday.

'Blindspot' Return Date: There's A Mole In The FBI! Will They Expose Jane's Big Secret?

The Bureau's tattooed enigma will keep her video confession to herself during the midseason premiere, instead choosing to keep her handlers focused on her inky network of clues rather than the mystery of her past (see a preview below). If the seemingly interminable hiatus has you itching for answers, intrepid fans can get a jump on "Cease Forcing Enemy" with the episode's first clue.

Weller's team will focus on a circular sequence of numbers this week, according to a photo from Entertainment Weekly. While the numerical code is important, showrunnner Martin Gero reminds fans that the area around the circle is also vital to solving the puzzle. Perhaps he's referring to the two little arrows the left?
