A side-story of the Rejuvenationverse.
Princess Cadence and Shining Armour are intrigued to learn of a less-than-untimely death of a prominent independent noble and the factors surrounding it.
The scent of murder draws them in to investigate.
Unravelled are the origins of the notorious royal, Blueblood.

A bit lighter than my usual work. Those of you who liked The Rejuvenation Play more than its sequels will probably like this.
Based on The Inspector Alleyn Mysteries books by Ngaio Marsh and the 1193 BBC1 series starring Patrick Malahide.
