Also Aaronovitch's style reads very flat after Wolfe's. Or maybe it's Tobias' voice, because I bet Peter's would have felt different, even though Tobias had some very Peterish moments.
So I reread Sorceror to the Crown instead, assuming Regency pastiche would have style enough to penetrate the heat-hazed brain. And it was well enough, though Zacharias is really such a-- err well, perhaps 'slave of duty' isn't the best phrase for it; so well-behaved and squashed a dutiful son that he seems almost as flat as Novik's Laurence. Really I much preferred Damerell. Especially as I'd remembered the deal with Georgiana but completely forgotten the one with Rollo. Shall go back and look at their passages again, only slightly hampered by not being able to remember the plot even a few hours after finishing the book.
