I both love everything and dislike nothing about these mysteries. I now can understand why the Endeavor series on PBS was also so well received. They stuck to a successful format. Unfortunately, the quality of the DVDs in this set is not that great. It seems like they are 420p at best. Some scenes are dim and even somewhat hazy at times but the quality of the performances more than make up for it. I'll rewatch them many times as I already have with the Endeavour series.
Listen for the code played at the beginning of the theme at the end of each episode. M O R S E _ _ _ _ _ . _ . . . . .
