Drake investigates the death of a secret agent, who has died in a mysterious crash in Sicily. Believing the agent was killed while investigating an arms smuggling ring, Drake is in for a bit of a surprise.

Nice 'twist in the tail' episode, but said twist is a bit obvious so many years on, especially given the actor involved in the twist. Murcell and Troughton make a fine pair of bullies. Odd to see such a quintessentially American actress as Garland in a British show, though.
