In this sequel to last year’s runaway one-man smash, veteran Fringe raconteur Chris Gibbs plays the dim-witted sidekick to a Victorian sleuth by the name of Antoine Feval, and spends the hour spinning a lengthy anecdote that keeps the listener pinned on the edge of their seat. Unencumbered by props, music or light effects, he works his way through a captivating mystery plot, veering off into an endless stream of digressions along the way. In fact, Gibbs is such a skilled improviser that he barely has time to do justice to the play’s ending, yet it somehow doesn’t seem to matter, because his endearing mannerisms alone are worth the price of admission.
