The Invisible Assistant

There's no question it was murder. But who killed whom?
What begins as a typical corporate event for magician Eli Marks turns into a twisted mystery when he is called to the site of a recent murder/suicide.
Confronted by the details of the grisly crime scene, Eli must sort through the post-mortem clues - and the bickering of the officials as well as a poorly-timed allergy attack - to determine just who murdered whom.
