"The Deborah Knott series, now numbering 21 books. This first book won an Edgar award for first mystery novel. They are all good books, well-plotted, lots of tension, and characters you care about. Not quite as important to read these in order as with some other series, but the personal relationships are better if read in order."

Sadly, there will be no more, as Bruce Alexander died in 2011."

Her ridiculously long name is Lady Victoria Georgiana Charlotte Eugenie, daughter to the Duke of Atholt and Rannoch. And she is flat broke.

But when her brother cuts off her allowance, she leaves Scotland, and her fiancé Fish-Face, for London. "
