This is a terrific historical whodunnit with some suitably gruesome murders and absolutely fascinating detail about life below stairs in l8th century London - and a very unusual crimebuster in a cook (whose recipes, incidentally, made me want to rush out and buy old cookbooks too). If you like a murder mystery that offers historical flavour alongside the crime, then this one is for you. Definitely rivals C J Sansoms Henry VIII whodunnits and I wanted to read her backlist as soon as I'd finished - author is, interestingly, an arts and antiques expert so her details are spot-on. And if you like this, I'd give Ariana Franklin a go too - her Mistress of the Art of Death; and Death Maze also combine history and crime with great results.
