The gripping sight of four burly policeman manhandling a bath down the front path of a respectable villa isn’t one the residents of Flaxborough see every day.
Net curtains twitch furiously, and neighbours have observations to make to Chief Inspector Purbright and Sergeant Love about the inhabitants of 14, Beatrice Avenue. Nice Gordon Periam, the mild-mannered tobacconist, and his rather less nice (in fact a bit of a bounder) lodger Brian Hopjoy had apparently shared the house amicably.
But now neither man is to be found and something very disagreeable seems to be lurking in the drains… Then a couple of government spooks turn up, one with an eye for the ladies – the drama is acquiring overtones of a Bond movie!
