This New Adventure takes the Doctor, Ace and Benny back and forth in time to crucial points like the murder of John Lennon and the sinking of the Titanic, on a trail originating in Mexico in the fifteenth and also twentieth centuries. There are consciousness-altering drugs and prose which reminded me of Ian McDonald, and a satisfying resolution to the pursuit of a mostly non-corporeal baddie. Interesting to read it while in the middle of listening to the latest Big Finish audios with the Seventh Doctor, Ace and their new team-mate.
