147

Conan continues his investigation, closing in on Keizo, his prime suspect in the stabbing death of his wife, Kayo. With all pieces of the crime in place, Conan understands the hidden truth and drops hints for the officers. Sato, Shiratori, and Takagi reveal that Keizo murdered his wife while at the police station; knowing his wife's routine, Keizo tied fishing line to Kayo's exercise bike and to a knife hidden in the bookshelf. When Kayo petals, the string winds up, pulling the bookshelf and knife down, effectively stabbing and killing her instantly. After arriving, Keizo directed the officers in one direction while he went to the crime scene and destroyed evidence. As proof, Keizo pricked his finger with a pin that releases the string causing it to bleed as he removed the bookshelf from his wife's corpse. Keizo confesses stating that he planned the robbery of his own bank for Kayo who lived a lavish lifestyle. However, she was held hostage during the robbery and recognized one of the culprits, which would eventually reveal Keizo as the mastermind. Two hours later, the robbers are arrested, along with Keizo. (Source: Wikipedia)
