Doug Moench, Gene Colan and Alfredo Alcala continue the twisted romance tale that Detective Comics has become with issue 544 (Sept. 84). The Night Slayer does appear in it, attacking Batman because of Nocturna’s interest in him, but he is not the focus of the issue, just the cover.
Nocturna continues her play for Bruce Wayne, now knowing that he is Batman. She offers to be his partner in both guises, still holding Jason Todd out as the cherry on the cake.
This issue does have a bit more action, when the romance needs a breather, but it’s still more soap opera than super-heroics.
Part of that means that things are moving slowly, and with the story jumping back and forth between books, it repeats itself, almost to the point of tedium.
This is not my favourite era for Batman.
