The dismembered body of a famous science fiction writer is found sans-head in a pool of purple water, requiring the team to turn to Zack Addy for help.
Tropes
- Idiot Savant: The victim turns out to have various social and mental handicaps, but was nevertheless a brilliant writer.
- Secret-Keeper: Sweets becomes this when Zack reveals that he didn't actually kill the lobbyist but just helped Gormogon catch him; Zack insists he has to keep the secret as he's bound by doctor/patient confidentiality and he knows he'll be transferred to prison if the truth comes out.
- Spotting the Thread: Zack helps identify the killer by observing various clues to point out that the victim's mother had her own mental issues involving a fixation with the number twelve, then drawing the team's attention to the only thing in her garden on its own (a birdbath) rather than in a group of twelve similar things.
