A con normally involves an element in which the Con Man gets the target to trust them and/or to focus on achieving their greedy ends such that it overrides their normal sense of precaution. This is a form of con where that hook is trying to entice them in on playing a con themselves. The process of the con gives the con artist many opportunities to feign cautious or try and entice the mark in feeling they have to prove something to the con man. The Con Within a Con can be controlled by having the fake target be a member of the con artists own crew (sometimes called a Napier). The pay off normally comes when The Con Within a Con requires the target to provide some front money which the con artist then runs off with.
