Initially starting with a premise of a young woman using her job to investigate the murder of her father that she witnessed as a child the story spirals into an ever darker tale of government programs and assassination programs. The protagonist is continually hallucinating, mapping Russian folk tales onto her games of cat and mouse with the retired assassins she is tracking down.
The reminds me of a more naturalistic version of Sam Keith with hair that swirls around the panel and limbs that zig zag away from the body to their terminus. The folkloric characters are vividly rendered and meshes the real and unreal satisfyingly.
The conspiracy plotline helps structure the four issues but towards the end it feels like ultimately this is just a story where people try to kill one another and as the truth of the protagonist's past is revealed things fall into place but not necessarily in a surprising way nor one that deepens or enriches the basic story. By the end I felt that this is probably a riff on the Black Widow origin story (which would also explain the name).
