Toasting Police

Space Police: The Toaster That Time Forgot
(Space Police #3)
by David Blake (2018)
Detective Inspector Capstan is asked to track down a mad and rather disgruntled scientist who’s just escaped from a maximum security prison asteroid. But when the scientist in question threatens to travel back in time to punish the person he feels responsible for having him locked up there, it’s up to Capstan and Dewbush to do whatever they can to stop him.

I think this is the best of the series (so far). The humour is very well done, and there is a great scene in a police station I could image on a TV series. Recommended.
