Three years ago, the New York Times published this article.

It was about “the fourth spy” at Los Alamos (in addition to the previously known ones, Klaus Fuchs, Theodore Hall, and David Greenglass)

What’s funky here is this line, right out of a movie:

In July 1945, the study reported, he was “part of a unit monitoring seismological effects” of the first detonation of the atomic device. His Soviet code name was Godsend, and he came to Los Alamos from a family of spies.

In case the “family of spies” bit seems far-fetched:

In 2012, Mr. Klehr obtained newly declassified F.B.I. files on informants who had successfully penetrated the Communist Party of the United States. Suddenly, he started seeing references to the Seborers, and major parts of the atomic puzzle fell into place: Oscar was Godsend, Stuart was Godfather and their older brother Max was Relative.

There you go. Like the Incredibles, just the … opposite, I guess.
