Roused by the insecurity of property, the authorities decided to import a London detective, disguised in plain clothes. He came, and for a while marauders, among whom the secret soon leaked out, carefully stayed their hands. After a time, however, robberies began to recur; especially a corner shop near "the far bridge," was the scene of considerable pilfering. ”
