Meitantei Conan S20E15 - Holmes' Revelation (Grass Court Queen)

Minerva is losing because she's writing a message in braille by hitting the ball on the lawn, which Conan understood. He convinces Apollo to give him his ticket. When he enters the room, he tells Minerva that he can help. Minerva believes it and keeps writing. The message said that the mother of Minerva was going to die. Conan focuses on finding Hades and asks Minerva to lengthen the game. Minerva gets to play and the party has to decide in the tie-break.
