All about suspense

Fingersmith, by Sarah Waters
This book is all about suspense . . . and lesbian sub-text, of course. Therefore, I must stop myself from saying too much, as I do not want to create even a hint of a spoiler.
The story concerns two girls. Sue Trinder is brought up as an orphan in Lant Street, London, amongst petty thieves and fences and con artists, sheltered somewhat by her unofficial guardian, Mrs. Sucksby. Maud Lilly's earliest memories are coming to consciousness in a madhouse, and then after the death of her inmate mother, being given to her creepy uncle who lives in a grand but isolated house. Maud's uncle uses her as a clerical assistant in his shadowy literary enterprise. Sue is persuaded by a con-man she knows as "Gentleman" to pose as a lady's maid to Maud in order to swindle her out of her inheritance. But nothing is at it seems . . .
If you love a good mystery, or a Victorian romance, or if you have lesbian tendencies and can take a really long tease if the culmination is worth it, then this is a book for you
