No doubt re-released by the BBC because it provides a credible a continuity-friendly explanation for why Winston Churchill and the 11th Doctor know each other in the TV show, this is a very plain, very simple adventure from Terrance Dicks. The prose is so sparse it's almost empty, which was appropriate for the episode novelisations Dicks grew a reputation for delivering, but lacking in an original novel. The plot itself appears to be the first act of a sequence involving the mysterious Players, who toy with human history for their own amusement, and so necessarily ends with little resolution. It's not all bad - the Sixth Doctor and Peri are very enjoyable here, and it breezes through established history with gusto. It's ultimately an empty read though, and isn't likely to stay with me for long.
