Please do yourself a favor and start this wonderful series at the beginning with Flora's Secret (originally titled Murder on the Minneapolis)! Unlike some series where book after book go by with little change in the main character, Davison's Flora has the kind of life that you really don't want to just jump in at with the third installment.
The year in 1903 and Flora is visiting London where she gets wrapped up in society, the suffragist movement, international affairs and, of course, murder. There are a lot of other things going on, as well, but we'll not get into those just in case you're a book or two behind. The long and the short of it, though, is that this remains one of my favorite historical mystery series and each installment is better than the last. Considering I gave the first one five out of five stars, we must be up to at least seven stars for A Knightsbridge Scandal -- and I feel that at least one extra star needs to be given for the addition of the spunky lady's maid, Sally!
