The Shadow War of Hawkman #3

Direct

Hawkman is saved from Fell Andar and his Thanagarian agents by none other than Hawkwoman, who later explains to Katar that it was Mavis Trent, disguised as Hawkwoman, who was killed by the Thanagarians. The Hawks sneak into Justice League headquarters in Detroit to try to erase any Thanagarian knowledge stored there before Fell Andar can get to it, but Fell has stolen Katar's spaceship and is heading straight toward them.
