When one of the great detectives of British television pays homage to one of the finest, if not the best of murder mystery writers, the outcome, can either be one of forced recoil, almost a cringe of mixed volatility, or as in the case of the Endeavour episode Terminus, can leave the armchair detective almost hugging themselves with glee as the script unfolds, loving the delicate balance created between sheer admiration and genuine impressive insight.
