Series: Part 5 of Dangerous Instruments
Sequel to Clockwork Murders. The happily ever after isn't always easy, but Coulson and Barton are determined to figure out how to make it work. After all, how difficult can it be to pretend to the world they're still just a gentleman and his valet, settling into a quiet life with no excitement or adventure at all?
More difficult than they anticipated, it turns out. And that's before Stark asks for their help tracking down a missing gem, people start disappearing around London, and Natasha resurfaces with a mission of her own for them. Their quiet life together may feature more dirigibles and explosions than they'd ever counted on.
