Secrets of the Dead is an ongoing PBS television series produced by Thirteen/WNET New York, which began in 2000. The show generally follows an investigator or team of investigators exploring what modern science can tell us about some of the great mysteries of history. Most programs incorporate primary source material, first hand accounts, dramatic reenactments, and computer-generated imagery (CGI) to tell the story. The series originated in a series of the same name in the United Kingdom first shown by Channel 4 in 1999. The first two seasons for each country were broadly similar, but thereafter diverged. The US series includes some programs shown in other Channel 4 series (e.g. Secret History). The case of originally British episodes, PBS re-edited, re-branded and finally re-narrated them with various American voice artists. PBS description: "Scientists seek to uncover celebrated mysteries of the past in this occasional British series.". The original series was made and produced in the UK and broadcast on Channel 4 from 1999. Episode topics have included the Titanic, D-Day, the Shroud of Turin, the Salem Witch Trials, Blackbeard's lost ship, and the first English translations of the Bible.
