from what I can remember and same from JANE S STAFF is that there is not set code it's just pot luck as each time you play the game it changes.

you could try these depending on how you did on the bridge

Push Nemesis off


A 4 right, B 2 right, C 2 left

A 1 right, B 1 right, C 2 left

A 1 left, B 2 left, C 2 right

A 1 right, B 3 right, C 4 left

or

Jump off bridge


A 4 right, B 2 right, C 2 left

A 1 right, B 1 right, C 2 left

A 1 left, B 2 left, C 2 right

A 1 right, B 3 right, C 4 left


Think I'll have a go at this classic again.
