Secrets of the Dead: Abandoning the Titanic

A selective critical checklist of notable Wednesday TV:

Secrets of the Dead: Abandoning the Titanic (10/9c, PBS, check local listings at pbs.org): Notwithstanding the James Cameron blockbuster, the tragedy of the Titanic has always held outsized fascination in the culture. PBS's engrossing historical series looks into one of the more mystifying aspects of the sinking: As the evacuation was underway, a nearby ship's lights were spotted, but to everyone's horror, it sailed away from them, leaving more than 1,500 passengers to a watery fate. What was this mystery ship? Secrets follows investigators who examine eyewitness accounts and records of vessel locations to get to the truth. (The 1912 inquiry that blamed Capt. Stanley Lord and the Californian proved to be incorrect.)
