Action Comics #595 (December, 1987)

Silver Banshee walked the streets of Metropolis, killing men indiscriminately as she searched a series of local bookstores. After one policeman under Maggie Sawyer's command was killed, and another nearly so, Superman finally showed up... only to die himself. Various parties, including members of Justice League International, mourned his loss. Black Canary and the Batman believed that someone should address the situation, while the Manhunter from Mars insisted, "Something must be done!"

Lying in state, Superman's ghost lifted from his glass encased body, stating "I have been cut down before my work was done! I must finish what I set out to do. Only then can I rest. Beware, Silver Banshee! Your time of judgment is at hand!" Jimmy Olsen had trailed the villainess to another bookstore, and nearly doomed himself when Spectral Superman showed. Once her powers failed to effect his immaterial form, she blew herself up trying to destroy him with her Banshee cry. Only after did a living Superman reveal himself, while his "ghost" resumed his nat-- er-- typical Martian form.

The Sleuth from Outer Space had deduced that there was a visual component to the Silver Banshee's powers that prevented her from killing someone that she couldn't accurately identify. The Kryptonian form held up better than human victims, but Superman was still placed in a deathlike coma state until the Aien Atlas jumpstarted his brain with undefined "mental powers." It's a huge stretch that doesn't stand up to scrutiny, since she'd killed multiple unidentified dudes, but Perry White lampshades it with "Well, I guess that's a satisfactory explanation... at least it'll have to do if that's all we're going to get." Still, they played fair by announcing J'Onn J'Onzz's presence earlier in the story, and allowing him a showcase for his detective skills.

"The Ghost of Superman" was by John Byrne, with Keith Williams. Crisis on Infinite Earths had ended with 1985, but it took until June of the following year for "Whatever Happened to the Man of Tomorrow?" to wipe the board clean of Pre-Crisis Superman. Then another four months later, John Byrne used the oldest but "spare" of his two Man of Steel titles to continue the team-up format of the recently canceled DC Comics Presents, beginning with #584. I'm fuzzy on when I started picking the title up, but most probably it was with this issue, so it would have been nice to already be familiar with Martian Manhunter for the reveal. It was apparently the first appearance of Silver Banshee as well, though I could have sworn she'd made an earlier one. Obviously she was super cool, and a fairly strong addition to the rogues gallery, so it's disappointing that she's been more or less relegated to a second hand Supergirl foil. Kal-El's so powerful and so visible that he really can't spare someone so formidable, just because neither Banshee or his cousin possess a y-chromosome.
