Charlie wants to find out if a string of fires was set by the same person. Larry tells Charlie, "If every arsonist approaches a fire differently, it makes sense that every fire set would be unique to the person setting it. Not just in terms of the method but in terms of the entire character of the fire. What we're talking about is a fingerprint for fires." Charlie calls this unique pattern a fireprint.
