My first fan fiction. It is set in the Wings of Fire universe after the events of Arc 3 where Thorn created the Operatails, a sub-branch of her Outclaws, that specialise in detective work researching the what, why, when and how crimes are committed in the desert kingdom. Our protagonist Brightsting, a new recruit inspired to join by his past, uncovers a coo and a very long string of murders from a seemingly invisible assailant and has to make a hard decision on which to pursue.
