This audiobook is narrated by an AI Voice. When a charming young couple lands a sumptuous London flat for a fraction of its worth, their friends can only marvel at their luck. But where others see a bargain, Hercule Poirot sees an impossibility - for no landlord surrenders such a prize without a hidden reason. As the little Belgian detective turns his celebrated 'little grey cells' on the riddle of the rent, a trail of stolen secrets and shadowy strangers winds from a cosy drawing-room to the brink of international intrigue, proving once more that the most innocent of bargains may conceal the deadliest of designs.
