It has long been speculated he used this time partly to create another ambitious work, "Le blog de Frantico", which was a comic strip blog published daily on the web for a whole year under the Frantico pseudonym. In interviews and on his web sites, Trondheim alternately admits and denies having written "Le blog de Frantico", though another author, Sébastien Lesage eventually stepped up and claimed to be the real author, saying he had asked Trondheim to help him maintain the mystery. To this day however, the true identity of Frantico remains unconfirmed.
