Gotham City Sirens #9

The Riddler makes a striking entrance on Guillem March's cover for this April 2010 issue, his sharp green suit and cane commanding the foreground as Catwoman, Harley Quinn, and a vine-wrapped Poison Ivy regard him from across what looks like a detective's office. The composition — Venetian blinds casting dramatic shadows, the partial "EDW—" sign hinting at Edward Nygma's new investigative trade — sets up a delicious tension between Gotham's most cunning puzzle-maker and the city's most dangerous women. Paul Dini writing this particular collision of characters is a genuine treat for fans of Gotham's darker corners.
