Kogoro has a lawyer client who is receiving death letters from someone with the initials "T.K.". When the lawyer ends up dead and a man with the initials "T.K." was a former client of the lawyer, the prime suspect is found. However, when they arrive at his house, he is also dead.

When Kogoro and Conan are waiting for Ran and Sonoko to finish shopping, Kogoro spots an attractive woman coming out of the phone booth. Conan spots a pen inside the booth, and tells Kogoro. Immediately Kogoro gets the pen and reaches to touch the woman--boom! Kogoro is knocked to the ground. Actually, the attractive lady was Satou-san in disguise! They were trying to capture the person who was attacking ""101 spice girls"". Sonoko comes to join Kogoro, but Ran stayed to get something else. Miraculously Ran winds up in the parking lot of the shopping mall and spots a body by a car--a dead ""101 spice girl"".
