An interesting idea! There is story out there somewhere, where in Doyle is sent undercover as a boxer, but gets badly injured in his fight, so Bodie has to go in to replace him.

I can't remember name or author - anybody out there? A question in Pro's Finder should help. https://prosfinder.livejournal.com/

I have read some of NR Walkers stories - but not this one. I'll have to take a look!
