The Damned Busters: To Hell and Back, Book I by Matthew Hughes
When mild-mannered Chesney Arnstruther accidentally summons a demon and causes Hell to go on strike, he doesn't expect to wind up as what he had always dreamed of being: the Actionary, a costumed crimefighter with a weasel-headed fiend for a sidekick. But that's just the beginning of a journey that will see the high-functioning autistic actuary enmeshed in the schemes of a greedy televangelist, romancing a pepper-spray-wielding manicurist, and sitting down to a poker game with the Devil where the stakes include his immortal soul.
