My vote goes for Suchet as well.
Back on topic, after The Luminaries, I felt like something shorter and simpler, so I read
Doctor Who: The Death Pit by A. L. Kennedy, the first in a new
Time Trips e-story series (each by a different author, much like the recent Doctor Who 50th anniversary series, but aimed probably at a somewhat older audience and not in strict order; this story, kicking off the series, starred the Fourth Doctor).
It was... okay. I didn't particularly dislike it, and there were some bits I enjoyed (and I thought the Forth Doctor's characterisation was pretty decent), but I also didn't really love it all in all.
