Lynvingen #5/1968

When a reformed Mark Desmond stumbles upon a Batman display at a department store, the sight triggers a terrifying relapse into his violent Blockbuster persona—now bent on destroying anything tied to the Caped Crusader. With Gotham’s streets in chaos, Batman and Robin must confront the man they once thought they’d helped, while Margot Rankin and James Gordon watch in dread.

When Martin Tellman summons the Mystery Analysts of Gotham City, he’s baffled by a sudden twist: his collection of what he thought were worthless copies of famous paintings has inexplicably transformed into the real masterpieces. With the Analysts—Kaye Daye, Art Saddows, John Burelson, James Gordon, Statsadvokat Danton, Hugh Rankin, and Bruce Wayne—rallying to unravel the mystery, the case takes a strange turn involving the Stonefellow brothers, Reginald and Ronald, and a curious art dealer, Haverford Mimms.

In "Lynvingens siste dager!", Batman and Robin are sent by Professor Carter Nichols to ancient Venice to collect crucial evidence—only Batman returns, while Robin finds himself stranded in Gotham City, days ahead in time, where he uncovers a chilling threat: a new criminal who will kill Batman.
