Gold on Crow Mountain

BBC children's tv viewers now in their 50s and 60s will recall this being shown in 1971 and 1973. English narration by Colin Jeavons told the story as the voices were not dubbed, only hushed. The hero Staffan finds some gold and some baddies try to get it from him. I recall a spooky couple who pursue Staffan and one of the cliff-hangers funds him arriving home only for them to be sitting in the living room awaiting him. Some very atmospheric music accompanied this too. Any other recollections?
