Thanks Andy! Yes this is a cracking piece of AH fiction! Very much on the 'suspension of disbelief' end of the genre, but Teddy Roosevelt charming and brawling his way through Victorian London to uncover the Ripper's identity is a great story, and Resnick tells it exceedingly well
Nice review. I definitely prefer the latter when it comes to 'accurate vs. 'fun'.
Reading the review, I was reminded of Houdini vs. Rasputin, another alternate history book involving divergent celebrities that wouldn't win any "most plausible AH ever", but was still a very fun ride.
