What's yours is mine

A good acquaintance or ours has just had her trust violated. Our friend, although from an older generation than us, is still very perky and shrewd. 
Last month her husband died after a long medical problem compounded by his growing forgetfulness. Her house has been a hive of activity, nurses, cleaning lady, carer to give her respite from the Alzheimer's Society. The house at times has resembled a major railway hub with all the comings and goings.
About two weeks before her husband's death she found her diamond rings were absent from their boxes. Was she going doolally - where could she have put them? She was about to go to the police but unexpectedly came across the rings in her camera case!!! but had no recollection of having put them there. She was going to visit her husband in hospital and decided to wear a gold chain he had given her when they were engaged over 60 years ago, but that was missing, her mind was in a flurry.
On inspecting her dressing table drawers she discovered lots of gold and silver missing, and several empty boxes. 
She let everyone that came to the house know her things were missing she became suspicious of everyone who entered, in particular the carer who looked after her husband. She came once a week for three hours to allow her to have an outing. During this time she had the whole house to herself with the husband mainly dozing in his chair.  She also had worries about the cleaning lady whom she knew had financial problems.
The lady from the Alzheimer's Society phoned just before her husband's funeral to say she could not attend but would like to come and see her the following week. They fixed up a date, and our quick thinking friend said "good, I would like you to be here because the police are coming to go through the CTV tape in the bedroom and I would like some company". The phone went quiet and the lady rang off. Several minutes later a text arrived saying "it was me, I am wicked, I will confess to the police". The lady was arrested by the police on the morning of the funeral, but has only admitted to taking two items which she has sold. At the moment our friend has discovered that at least 16 items are missing, but wakes up in the night wondering if she has accounted for everything.
Today she is confronting the cleaning lady in her own inimitable style, the insurance assessor is calling and so is a representative from the Alzheimer's Society.
She told me she has not had time to grieve her husband, her mind is completely taken up with so many tasks and questions whirling around in her head.
They have no family of their own, so who would know what was in the drawers and boxes when she dies? As I said at the start her trust has been violated.
As a timely warning I would like to suggest that you photograph your precious belongings. It is very important to have a record and it is also something that can be very helpful when making a claim to your insurance company should the need ever arise.
