It's all so strange that no one raised the alarm for all that time. I wonder if their phones were with them and no one could hear them ringing from the house, if there were staff in the house. It's hard to believe that no one had tried to contact them. I think even if I had been told not to service the pool area I might start to look for them there in case one of them had fallen or had a heart attack and needed help, with the cars being outside and them not having said they would be away, not coming to the kitchen for food or drink, not picking up their mail, and not being anywhere else in the home. Staff would probably be best placed to immediately know what was out of character. I think it's odd that they didn't look, if they were there on Thursday and/or Friday morning, even if it was outside their normal range of duties to go there. I might even have gone to a neighbour to ask if they had seen them and allow the neighbour to come in and look.
