This surprised me a bit, but the Black Bat book did skip a month recently. Dynamite has a history of falling behind with books, so I assumed that they were trying to avoid to promote a book they knew full well they would not be able to produce on time, for whatever reason.
The publisher has finally updated its website to include the solicitations and Noir #4 does appear among them. So maybe they just didn't submit it to news outlets earlier in the month. Regardless, it's there now and presumably will be available on time. There was also an alternative cover to Black Bat #9 revealed, which I've displayed at the bottom of this post.
NOIR #4 (of 5)
Writer: Victor Gischler
Art: Andrea Mutti
In the Labyrinth of the Templars, The Black Sparrow and Miss Fury follow the deranged villains Orlando and Minerva on a trail of a lost treasure. Along the way, they dodge traps and pitfalls and learn of the Templar connection to the Mohawk Tribe. Will the ladies be forced to join forces with the bad guys to attain their goal, or will one stab the other in the back at the first opportunity. Blazing guns, snapping bullwhips and the looming shroud of betrayal await you in the next issue of Noir.
