Irving Lambert

Colonel Irving Lambert was a character from the Splinter Cell Universe.

He was voiced by Don Jordan in Splinter Cell, Chaos Theory, Double Agent, and the flashbacks of Conviction, and is voiced by Dennis Haysbert in Pandora Tomorrow.

Irving Lambert was the first Director of Third Echelon and was the best friend of Sam Fisher. In 2008, while working undercover, Fisher ended up killing Lambert in order not to blow his cover.

In 2011, Fisher finds out that Lambert was the one that had the former's daughter's death faked. Reason for this is that Lambert discovered the presence of a mole inside Third Echelon and that the mole would use Sam's daughter as leverage, potentially compromising Sam and Lambert couldn't allow that.

After Lambert's death in 2008, the mole, revealed to be Tom Reed, took control of Third Echelon in 2010 and corrupted the agency.
