Sherlock and Watson find a body split in half during ballet rehearsal.
Tropes:
- Feet-First Introduction: We see a woman's bare feet padding out of Sherlock's bedroom following a night of lovemaking. The woman turns out to be Iris Lanzer, the prime suspect in the murder Sherlock and Joan are currently investigating.
- Half the Man He Used to Be: Poor Nell Solange's body was cut in half at the waist post-mortem by the ropes tied around her.
- Pun-Based Title: From "corps de ballet".
