Department S

Stewart is a spectator at a golf tournament in Scotland. When the leading player, Eddie Curtis, fails to show up for his tee time and is disqualified and later found dead, it is labelled an accident, but Stewart suspects foul play and investigates on his own.

Annabelle's research leads the team to the casino that the chip came from, and when Stewart and Jason check the place out, the croupier recognizes Stewart from an earlier encounter, and now the stakes are high - with Stewart gambling for his life while hoping the cavalry will show up in time...
