Who does Aunt Sally blame for the loss of all the items found missing? CH 34-38

Aunt Sally notices that she has lost a sheet, a shirt, six candles, a spoon and a brass candlestick. Very confused by the strange disappearances, she becomes absolutely livid. Aunt Sally yells at poor Silas, who eventually discovers the missing spoon in his pocket, where Tom had placed it. He looks ashamed and promises her he has no idea how the spoon got into his pocket.
