Having quite enjoyed The Clockwise Man, I had high hopes for The Deviant Strain. Unfortunately, I was left disappointed, and it’s hard to pin down exactly what went wrong—there’s just something that doesn’t quite click.
The setting is drab and uninspired, lacking the atmospheric charm or intrigue that makes a good Doctor Who story come alive. The characters, too, fall flat. They feel like one-dimensional stereotypes rather than people you care about, and this is especially noticeable because for much of the book, the three main companions—The Doctor, Rose, and Jack—are separated. As a result, the dialogue often feels impersonal and shallow, with much of the focus shifting to side characters and strangers who aren’t compelling enough to carry the weight of the story.
This separation particularly hurts the dynamic between The Doctor and Rose. When they’re apart, they each come across as surprisingly dull—stripped of the spark and warmth that make their on-screen relationship so enjoyable. Jack, on the other hand, is featured heavily, but oddly, he feels quite unlike his TV counterpart. He’s missing the usual roguish charm, quick wit, and layered personality, and instead comes across as a flat, generic action man.
One of the more jarring elements of the book is the sudden tonal shift from investigation to full-on “run for your life” survival. While this kind of transition is something Doctor Who has done successfully many times, here it feels clunky and mishandled. The pacing suffers as a result—the first few chapters drag badly, and although things briefly pick up in the middle, it never really finds its footing. It feels like the author couldn’t quite balance the investigative and action elements, and if that was the case, he might have been better off sticking with one tone and seeing it through. Again, comparing it to The Clockwise Man, which was around 90% mystery, that consistency worked in its favour and delivered a much stronger narrative.
The actual plot itself is bland—almost like watching a silent black-and-white film. It’s a shame, because I genuinely love the Ninth Doctor and always have high hopes whenever he features in a story. But in this case, it barely even feels like he’s present. The writing doesn’t capture his energy, intensity, or cleverness, and it ends up reading more like a generic sci-fi story with Doctor Who characters dropped in after the fact.
Overall, The Deviant Strain is a dull and forgettable entry in the Ninth Doctor’s line-up. It lacks the heart, energy, and cleverness that usually make Doctor Who books enjoyable, and worse—it lacks personality. In a universe bursting with possibilities, this one sadly just doesn’t deliver.
