If we assume that Meruze is not insane simply because he is confined to an institution for the mentally ill, nor because he dispensed justice against a liar by first visiting the shop that advertised: FARCES ATTRAPES COTILLONS (costumes and masks), then we would not be far from the truth in assuming that he will wear his mask in vain, although in time to play a farce before a charlatan like Charles Huguenin, who repeated to a distressed customer, ‘No, no, and no, listen, Peyrolles, if you don’t pay by tomorrow, I will take legal action… a contract is a contract…’ He asks him for 100,000 in two cheques and his car to return to Lyon, but once he leaves, the businessman notifies the bank and asks the operator to listen to his urgent request. When the masked man returns, he is about to shoot him for being a liar, but the police shoot him first. It turns out that just as they were taking the logical offender away in handcuffs, Peyrolles telephones and gives him time to pay everything in front of the police and the detainee. ‘Liar, liar,’ can be heard in a din.
