"Luthor knew!"
The Covers at time can be miss leading, Solomon Grundy does not have much to do with this comic. The whole Suicide Squad does.
The Premise of this story is Lois is trying to bring down Luthor with an article she is working on, but she can't work on it because of an agreement with Luthor. The Suicide Squad show up to "Scare" her. This issue does set up interesting ideas and makes me want to know more about the political tension between Clark Kent and Lex Luthor. The conflict boils over by the end of the issue with Lois and Clark finding a loop hole to Lois' agreement.
This comic was collected in DC Comics Presents: Superman #3. Because it is the end issue to a multi-part story, I think it was silly to leave that collection so open ended. The issue is not bad for the collection, it just seems weird to leave the collection on a cliff-hanger.
Cheers!
