Sherlock Holmes caught three thieves; Robert, Walter, and Frank. Each of them had robbed a house in a different part of London at approximately the same time. Robert, who was the oldest, didn’t commit his crime in Ealing, and Walter didn't rob the house in Clapham. The one who robbed the house in Ealing didn't steal the gold watch. The one who robbed the house in Clapham stole the painting. Walter didn't steal the silver coins.
In what part of London did Frank commit his crime and what did he steal?
