Murder in Old Bombay by Nev March

This is a deeply romantic series of adventures in the pursuit of solving a mystery. There are references to Doyle, it's possible the author wants people to think of it as a mystery of ratiocination, but while the resolution is well-handled the mystery isn't the strongest plot here--there's other, more interesting stuff going on, and that's fine. Sara had checked this out from the library, and I can definitely see why she stayed up late reading it.
