Murder.  A word not heard in Equestria in a long, long time.  Perhaps not since the Princesses ended ancient conflicts and brought the three pony races together in harmony.

But there is a new race in Equestria now, one not so unaccustomed to violence.  The terrible task of unraveling a horrible crime falls to Shining Armor, and against his wishes, finds Twilight volunteering her help.  All the resources of the Royal Guard are available to them, but will that be enough to keep anyone else from dying?  

Rated and tagged as such to be on the safe side.

(Several chapters edited and re-written.)

After more and more humans began arriving in Equestria, the Princesses commissioned a guide to be written for new visitors to help them acclimate to life here with ease.

Containing sections on various topics including magic, Equestrian history, language and employment opportunities for humans, this guide will help day-to-day life go smoothly during your time here.
