Martin McCaffrey is a Night Vale resident who works at the airport as a TSA representative. He urges the townspeople to accept the new security measures at the airport even though they appear onerous.
In his personal life, Martin is greatly distressed by the mysterious sketches that constantly appear near him. The sketches are all of a strange, elongated dark figure crawling out of a refrigerator. Though Martin claims he does not understand who is drawing the sketches or what they have to do with him, eyewitness accounts strongly suggest that he draws them himself and cannot remember doing so.
He once ran TSA at the Night Vale airport, but he was stressed and unhappy, as he kept seeing mysterious dark elongated shapes. After being convinced that only a higher power could protect him form the shapes, he joined the Joyous Congregation of the Smiling God and got involved in its practices, helping to organize church camps. After a few years he left the church as it didn't met his expectations, and learned to accept the dark shapes.
