The Witch Who Came in from the Cold is a serialized alternate history fantasy publication by Serial Box. Like all Serial Box productions, it is available as an audio drama and an ebook. A print version is also available. The story is set in Prague in 1970, just after the Prague Spring. CIA spy Gabriel Pritchard engages in espionage against the KGB, particularly against Russian agent Tanya Morozova. His work is compromised when he is embroiled in a conflict between two warring groups of sorcerers known as the Ice and the Flame, who have infiltrated the intelligence agencies of all major world superpowers. Gabe and Tanya's loyalties to their countries and magical allies are tested as each group attempts to seize control of a Russian defector, who also happens to host a powerful elemental spirit. The story was followed by a second season in 2017. A third season is in development, but as of June 2018 it had not been greenlit.
