Excellent! Perhaps look into a sequel where Hermione finds out Heyes was great, great grandfather.

Odd crossover, not the oddest I’ve ever seen, but a pairing I wouldn’t expect.

"Hello, my love, where have you been all my life?" My favorite line; and some how I get the feeling this went through Heyes' head every time he came across a new safe. Such a good blend of ASJ and HP. Would like to see more.
