Second paragraph of third chapter:

Ruth Winters looked up from reading a report; her lips pressed tightly together, her eyes narrowed.

Another in the sequence of Lethbridge-Stewart novels where the Brigadier and two of his friends have had their consciousnesses sent wandering back along their timeline. This was not one of the better ones. A surviving Dominator from earlier in the series is mixed up with organised crime and Nazis in 1973 London, while the events of The Silurians and Ambassadors of Death take place elsewhere. Really annoyed me by misspelling a couple of German names – Bormann becomes “Boorman”, the Ahnenerbe becomes the “Annenerbe”; I think putting Nazis into a 1970s spinoff Doctor Who story is lazy anyway, but not getting the German words right is positively indolent. Anyway, you can get it here, and I look forward to the end of this rather disappointing subsequence in what has generally been a good series.
