I was tooling around with some ideas the other day about the big finish in the climactic showdown. The heroes know of the evil plot and the night before they hatch their own plan to hijack the enemy's plan. My question is how would it work if I didn't want to show them making the plan, but instead just had "I have an idea", then cut away so that the reader doesn't know what the plan is until it's carried through in that climactic moment. Would the reader dislike having this information withheld even though I think it makes for a more powerful scene in the end? I feel like explAining the plan before the battle may steal some of its thunder. Any experiences with this sort of thing? Comments? Thoughts?
