Leger's Bubble

You might think that with Scotland locked down and nobody able to get in or out of their homes that there would be no crimes to solve. Leger certainly did, until one happened under his own roof. There are currently six humans staying in his home, including Annabella. As they all have chronic health conditions and require to "shield" they have gathered together to form a bubble with their pets and live together so they don't get lonely. Then Leger notices that £2,000 that Annabella had foolishly hidden in her bedroom has vanished. Nobody has come or gone from the house, so one of the guests must have stolen it. The question is, which one and how will Annabella react when one of her closest, most trusted friends turns out to be a thief?
