1 Dr Evil (Open Lynchpin-Mastermind)
7 Guard Minions (Doctors)
2 MI6 Agents (Vig)
Town wins if all Agents are eliminated.
Mafia wins if the Lynchpin is eliminated.
Idea is that Dr Evil decides which minion to lynch each day, and is openly revealed. Everyone else has the obvious safeclaim of Guard Minion.
Each night the Agents pick off guards or make an attempt against Dr Evil, while the guards try to distribute themselves so that at least one townie is guarding the lynchpin and the rest protect each other.
There will always be at least one unprotected target, and if town organizes too much, the agents can easily pick off that vulnerable player without losing their cover.
Obvious safety strategy is to get ScumCount+1 players to agree to guard the lynchpin, but that leaves multiple unguarded guards and the agents will know that.
Players not wanting to personally guard the boss might be indicative of scumminess since that leaves more guards unprotected.
