Kind of an insubstantial read for me. The mystery didn't really hook me too grandly, I felt we weren't given enough of Lacey to get to know him well, and the various reveals towards the end felt a little bit clunky and rushed.
I liked Grenville, though.
A nice filler read, but not something I could sink my teeth into. I might well end up grabbing the sequel(s) to have something easy to flick through when needed - and because I'm really seeing The Hanover Square Affair as an introductory book to outline characters, rather than a full-blown tale in itself.
Hoping we get to know Gabriel Lacey a bit better and that he gets his life sorted out, really.
