Meant to be a humorous short, fanfic, on Will Herondale and Jem Carstairs, in the Infernal Devices, written by Cassandra Clare. Starring the parabatai, Henry, Jessamine and Gabriel. They find something in the crypts, where Henry works, and think up of a prank to do on Gabriel. I do not own the rights to the Infernal Devices or its characters. The characters are about 14 or 15 years old, as it is after the parabatai ceremony.Public Domain
