Loved the opening of this - too much hollandaise is indeed a crime, hangover or no hangover.
From the Blurb:
One spring morning a woman is found dead in a Brunswick alley adorned with symbols of the occult. Catherine Kint, milliner, gin enthusiast and raconteur, has no reason to be involved until her friend is under investigation. Armed with her sharp wit, a crime scene background and a barman named Boris, Catherine walks into a world of new age prophecies, curses and money. Honestly, it would drive a girl to drink.
