Winter won't be a very good time to be a spy in the Marvel Universe thanks to writers Jim McCann and Duane Swierczynski. The pair will be collaborating on Widow Maker, a four-part crossover that will take place in HAWKEYE & MOCKINGBIRD #7-8 and BLACK WIDOW #9-10 starting in December and running through January.

This is what Marvel.com has to say about this crossover between these "spy titles".

These two titles launched not too long ago and about the same time, so to me it makes sense to have Black Widow in the Hawkeye & Mockingbird title since Clint and Natasha have some history together.
 
Personally I haven't been reading the Black Widow title but I have heard it's a good series so far, and as for how McCann's Hawkeye and Mockingbird stories have been, all I can say is that this title has become a favorite of mine just two issues in.

A very familiar face-or rather mask-has been killing spies from different agencies and has their sights set on Black Widow and Mockingbird
"[The killer is] wearing a very familiar costume: the Roninsuit," McCann reveals. "As for who is inside of it taking out spies and heroes all over the world, the motives for that, and the person pulling the strings, you'll have to read it to find out!"

"I will give you one hint: If someone's taking out/neutralizing spies all over the place, it would stand to reason that someone, somewhere, wants the world temporarily blind and deaf," the writer teases. "But for what?"

"Seriously-McCann is a madman," Swierczynski says. "His ideas and the crazy stuff he dug up from true-life espionage cases are going to make this crossover one to remember. I'm already hoping for a sequel: Widow Maker 2: Widow Harder."

I'm excited about it. I love the Hawkeye and Mockingbird series out. Its been good to me so far and I hope the stories  keep going. I want to see this series continue to run far with things. Having someone looking to killing spies would be great and to see if Dominic Fortune (if Clint lets him live long enough) tries to play it up that it's Clint trying to kill bobbi back in his Ronin mask. I haven't read the new BLack Widow comic either but if i might go pick one up to see how things are before the crossover.

I absolutely love the new Hawkeye and Mockingbird series. McCann has such a great respect for both of these characters. He pays a attention to their past continuity and tries to weave it seamlessly into there present. He really writes the characters how the should be written he adjusts his writing to the characters not the other way around. So very often recently we see characters written out of character to suit the creators needs, but this isn't certainly not the case with McCann. The art has been great as well. I haven't been buying the new Black Widow series because I am not a fan of Acuna's  art but when the new creative team take over I will be picking it up. I kinda needed a break on Black Widow after that terribly written mini by Paul Cornell.

I like crossovers, and this one sounds awesome, but I hate having to pick up extra issues just to get the whole story. In a way, it is a bit of a gimmick to get people to pick up more comics.
