Birth of a series

My friend pointed me towards a new Victorian-era mystery series by Deanna Raybourn, featuring two sleuths -- one a newly widowed lady from an eccentric titled family, and the other a gentlemanly but taciturn sleuth with a mysterious past. Sounds unoriginal, but very well written, and with actual character development. Great treadmill reading. Two are out already, and hopefully it will be a long series.
