It did not require a deal of keeping. Battersea may have its tough citizens, but they do not live in Battersea Park Road. Battersea Park Road's speciality is Brain, not Crime. Authors, musicians, newspaper men, actors, and artists are the inhabitants of these mansions. A child could control them. They assault and batter nothing but pianos; they steal nothing but ideas; they murder nobody except Chopin and Beethoven. Not through these shall an ambitious young constable achieve promotion. At this conclusion Edward Plimmer arrived within forty-eight hours of his installation. He recognized the flats for what they were--just so many layers of big-brained blamelessness. And there was not even the chance of a burglary. No burglar wastes his time burgling authors. Constable Plimmer reconciled his mind to the fact that his term in Battersea must be looked on as something in the nature of a vacation. He was not altogether sorry. At first, indeed, he found the new atmosphere soothing. His last beat had been in the heart of tempestuous Whitechapel, where his arms had ached from the incessant hauling of wiry inebriates to the station, and his shins had revolted at the kicks showered upon them by haughty spirits impatient of restraint. Also, one Saturday night, three friends of a gentleman whom he was trying to induce not to murder his wife had so wrought upon him that, when he came out of hospital, his already homely appearance was further marred by a nose which resembled the gnarled root of a tree. All these things had taken from the charm of Whitechapel, and the cloistral peace of Battersea Park Road was grateful and comforting. And just when the unbroken calm had begun to lose its attraction and dreams of action were once more troubling him, a new interest entered his life; and with its coming he ceased to wish to be removed from Battersea. He fell in love.
