Spoilers!
The Foxglove Cylinders, like His Close Companions, is just a bit of an odd War Master story. For one thing, the Master doesn't actively do anything Master-ish. It's extremely unclear what his goal is, what he's done in the past, and why he's even interested in a wax cylinder that presumably contains information he could find in his Tardis. Plus, it's just sorta unclear in the story itself what even was going on; I still don't fully understand the last five minutes. The premise here is decent, but in my view this is just a much worse version of The Life and Loves of Mr. Alexander Bennett. This isn't a terrible story, but it's an odd script for this range.
