The Chest of Silver

Raffles tells Bunny that he is going off to Scotland to improve his Scots dialect. During his absence his rooms at The Albany will be renovated, and it becomes imperative that certain items are not found in Raffles' flat. Therefore, Bunny is entrusted with a chest full of silver, and Raffles requests that he lodge the chest of silver with the Bank. Bunny complies, but are things quite what they seem?
