They saved Luthor's brain!

Superman's greatest enemy, Lex Luthor, is dead. The most powerful man in Metropolis -- bar Superman -- has been consumed by his own dark desire to see the Man of Steel destroyed.

To the world at large Luthor was a businessman, a philanthropist, the man who made Metropolis.

Only Superman and few others knew of the heart of darkness that beat in his breast, but now even that has been stilled.

Luthor's brain, however...well, that's another matter altogether.

When the mysterious, and hitherto unheard from, Lex Luthor the Second lays claim to the Luthor inheritance, Superman begins to suspect that his nemesis may have found a way to reach from beyond the grave, with lethal intent!
