Hush stars in Detective 852 (March 2009), as the villains take over the various books this month, as part of Faces of Evil. The story, by Paul Dini, Dustin Nguyen and Derek Fridolfs, is also part of Last Rites, stories set in the immediate aftermath of Batman’s apparent death.
Hush emerged from the river, after escaping the Whirly-Bat crash in the cave, and was immediately mistaken for Bruce Wayne. This proved to be a great advantage in getting helped out by everyone he encountered, all hoping to make a good impression on the billionaire.
Tommy heads to an exclusive club, and allows himself to be picked up by an older socialite, who he knew through her plastic surgeries.
She is delighted to be spending time with Bruce Wayne, and they head to her yacht in the Caribbean. Hush promptly murders her, and sails to Australia.
He heads to a Wayne facility there, and passes as the big boss, taking out a giant wad of cash from the company to support himself. He runs into Tasmanian Devil on the street, but tries to avoid him, unsure if the former Justice Leaguer is aware of Batman’s identity.
Playing it safe, Tommy leaves Australia and heads to VietNam. But that proves to be a bad decision, as he winds up in the hands of Catwoman.
The story concludes in the next issue of Batman.
