Wow, wow, wow.  Just a sublime, perfect, engaging audio experience overall.  What an exquisite way for the now final appearance of Murray Melvin as Bilis Manger who sadly passed away before this audio was released.  Everything I've touched of the War Master series has just been so fun so far.  I just adore how the Master is immediately put on the back foot by Bilis' appearance.  We get a better sense of what this mysterious Bilis character is and how the Time Lords view his, while enjoying the cat-and-mouse game that begins as War Master is incessantly followed by Manger after accidentally unleashing him on this world.  The setting has a lot of detail to that that adds to the stakes while the pacing and atmosphere fill The Sublime Porte with a lot of tension.  I really, really like how this story treats both War Master and Bilis' character overall.  James Goss was the perfect choice for this script as he really has a handle on both of these characters and Big Finish was more than ready to live up to the script he created.  I highly recommend this one.  It stuck with me in a big way.
