Full Circle - S1.E13

The Karadia brothers run a carpet factory which has suffered more than its fair share of fires. The police, fire brigade and insurance company suspect arson. One of the carpets which is destroyed in the latest fire belongs to Harry - he has ordered it for The Grand and is worried because he has over-estimated its value on his insurance claim. Ken follows the suspected arsonist to a new hotel that Harry is about to buy and catches him in the act of setting a fire. Both Ken and the arsonist narrowly escape with their lives.
