Dangerous to Know is the 5th in the Lady Emily Hargreaves series of light historical mysteries. I liked it better than Tears of Pearl, but didn't find it much more believable.
The mysterious Sebastian continues to be the most interesting character--much more interesting than Lady Emily and her husband Colin. The first three books in the series were fun, but these last two haven't been nearly as much so.
Tasha Alexander had been compared to Laurie King and Deanna Raybourn, but King and Raybourn are much better at plot and characters.
