This is a novel created from Douglas Adams' long lost TV script for Tom Baker's Doctor Who, an episode which was never filmed. The author/editor Roberts has painstakingly reviewed the old scripts and notes and pretty successfully untangled a novel out of it. I haven't read any other Doctor Who novels so I don't know how this one compares, and it's been many years since I watched a Tom Baker episode of Doctor Who. This feels pretty true to the Tom Baker Doctor I remember, and there are echoes of Douglas Adams in the humor, but his full tone doesn't really shine through. I assume this is because his writing was originally as a TV script and Roberts has added the novel narrative, which is where Douglas Adams' wit normally shows itself in the absurd details and side notes. Roberts has done a decent job however and it's an enjoyable and interesting read and worthwhile for a Douglas Adams fan. I can't decide between giving this 3 and 4 stars; ideally it would be 3.5 I think.
