Frank injured books?

[Brainysheep66]

Looking for HB books, any except the oldest version as I prefer the more serious tones such as in the undercover series. Looking for any moments where Frank is injured, kidnapped or in quite serious danger, bonus points if Joe is worried or concerned. Thanks in advance, anything you can think of!

Frank has hypothermia and Joe has to nurse him back to health, as he's concerned he could die otherwise in The Hardy Boys Survival Handbook.
