The stuntman (either Alf joint or marc boyle) playing Sherlock Holmes in the final problem was laughably unconvincing during a wire assisted fall especially when whoever played moriarty was all the more believable

 

Right up until the piss poor out of sync dummies dropped into the bottom of the waterfall, which was sort of to be expected anyway

 

Yes if you don’t know I’m watching the excellent Jeremy Brett playing Sherlock Holmes on DVD
