" Fifth of the New Who novels, with Nine, Rose, and Captain Jack. A Neanderthal turns up in 21st century Bromley, and the Tardis crew turn up to investigate why someone is using a particularly primitive, and stupid, method of time travel in the area. It transpires that there's no way to take Das the Neanderthal home without killing him, so Jack gets detailed to teach him how to survive in present-day Bromley, while the Doctor and Rose go back 28,000 years to find the source of the problem. What they find is a historical research project by a group of humans from Rose's future, and some very nasty things hiding in the project's storeroom...[return][return]It's an engaging enough story with some good one-off characters, although the Big Bad feels a bit cardboard to me. One of the best bits for me was the sequence of paired diary entries from Das and Jack, showing their very different perspectives on 21st century humans and each other. Often very funny, and occasionally poignant, and while I don't think they'd have supported a full story in themselves, I would have been glad to see more of them. "
