I don't know Modesty Blaise, unfortunately; I don't think I've ever encountered a fandom by that name before ....?

(I did mean to get to your prompt a lot sooner, but, well. I didn't write at all this spring, grief being what it is, and the muses have been idiosyncratic since. But I did manage to reread canon and take lots of notes. November's gonna be busy, but I'll get it done.)

The Tony Stark prompt ... I don't think I've done the lost family route with the Avengers before; sounds like fun!
