This year sees the 45th anniversary of Doctor Who, and to fit the celebration, Big Finish plan to release this week a rather special audio play. The aptly named “Forty-Five“ is a series of four adventures on 2 CDs from some new writers to Big Finish, featuring the Seventh Doctor, Ace and Hex.

The following is the synopsis of the plays in the 45 release:

2. ORDER OF SIMPLICITY
by Nick Scovell

3. CASUALTIES OF WAR

4. THE WORD LORD
