I have to ask the script writers to explain the overnight Container Ship crossing from Costa Rica to Bristol Docks which obviously is the better option than flying these days! Also, did the senior policemen's Mammy do his tie for him so that he could pull it on and off over his head each day? Clip-on ties are mandatory in the service for obvious reasons and they look a lot smarter than that granny knot loosely hanging around his neck. Absolutely pitiful directing, nonsensical continuity and woeful acting but how we all laughed at mother's deadly shooting accuracy at a moving target over 100 metres away from an upper floor window but missing the elderly female detective at 3 metres max. who recovered with her arm in a sling in the next scene. Ernie Wise would have "wrote" a better play!
