Observations

On average just over twelve actors appeared in each episode. However there were wide variations, with twenty three featured in The Next Voice You See down to only seven in Once the Killing Starts and A Killer In Every Corner. Notably the average cast size of the episodes from Good Salary - Prospects - Free Coffin onwards was somewhat larger, though reverting to a small number in the very final story - Death In Deep Water. It is possible the larger casts reflected higher budgets.
