Five-leaf clover

The five-leaf clover was a type of clover which was sought after by Irishman Pat Kelley.

In search for the clover, Kelley travelled aboard his spaceship, the Emerald Isle, to the planet Skaro where he bluffed the Golden Emperor into allowing him to stay in the Dalek City where he could look around. Upon meeting with the Emperor again, Kelley complimented him on their hydroponics chambers and made special note of their clovers. Reasoning that Kelley must be a spy and that he noted the clovers because he knew they would grow quickly, blocking their metal roadways and strangling their machines, he had the Emerald Isle fitted with the clovers to bring certain doom to Earth. The Daleks allowed Kelley to leave and after hearing Kelley's seemingly happy reaction, the Emperor remarked that he was probably undergoing the last stages of insanity. Little did he realise however, Kelley had infact been playing an elaborate ruse to acquire the clovers all along. (PROSE: The Five-Leaf Clover)
