Conjure Excuse

A Ghostly Voice tells you a simple, yet plausible excuse to get out of an unwanted situation. It holds up under simple investigation, but might falter if closely examined. 

You magically gain knowledge of  events involved in the excuse, as though heard through rumors. (Such as an accident on a road you did not travel, an upcoming party you did not hear of, etc) (The DM chooses what information the excuse entails and is revealed to you) 

 While telling the excuse to an NPC, the DM may have you roll for deception, if so you add your spell modifier to the roll.
