الموسم 2، الحلقة 4: At a quaint sidewalk cafe, Serge Cluvarias and his young date Ariana sit enjoying a late dinner. Their quiet evening is suddenly interrupted when a mysterious masked figure dressed as a ninja leaps down into the cafe from the rooftops above, and, without warning, shoots Serge dead. The ninja then makes a quick escape by leaping onto the restaurant awning, performing an amazing in-air somersault, and diving into the street to run away. When the police arrive at the scene with Monk in tow, it only takes the obsessive compulsive detective a moment to tie together a handful of clues. Sugar cubes missing from the tables, sawdust on the ground, a somersaulting ninja, and an elephant gun... is there a circus in town? Lolita Davidovitch guest stars.
