The Sweepstake Murders

Nine men formed a sweepstake syndicate. One man died. To forestall legal argument they agreed that only living members should share any winnings. They won £241,920. And then the deadly arithmetic began. Nine less one left eight shares worth £30,240; Eight less one left seven shares worth £34,560; Seven less one left six shares worth £40,320; Six less one left five shares worth £48,384. Who was killing for profit? And who would be left to collect?
