★★★★ The letters CSI stand for, in case you’ve forgotten, crime scene investigation. CSI, these days, is a television franchise responsible for programs that reach about two billion people. True CSI presents semi-doco versions of true stories. Participants may not be as groovy as in LA or as tanned as in Miami, but the dead people (two respected professors) really are dead. Might those bloody footprints be a clue?
