Jennifer Beals is heading to 'Castle.'

Beals, who viewers last saw in 'The Chicago Code,' will appear in two episodes of the ABC drama as Sophia Conrad, "a smart, commanding and sexy CIA operative," TV Guide reports.

Beals' character has a past with Richard Castle and joins him and Beckett to search for a CIA agent who has gone rogue. The rogue agent is a key suspect in a murder case Beckett and Castle are trying to solve.

Beals' episodes will air as a two-parter in February.
