内容简介：
A brand new Poirot omnibus, featuring four of the world-renowned detective's most challenging cases: The Murder of Roger Ackroyd, Murder on the Orient Express, Murder in the Mews and Hercule Poirot's Christmas. It seems Hercule Poirot can never escape murder -- and in this collection, the crimes are probably the finest he has ever had to solve. Locked rooms, wealth and jealousy -- outwardly all very similar, but when the detective begins to dig, the motives and solutions couldn't be more different! The Murder of Roger Ackroyd In the quiet village of King's Abbot, a wealthy widower is found stabbbed to death in his study! Murder on the Orient Express A wealthy American dies of multiple stab wounds on a train bound for Paris! Murder in the Mews A widow is murdered in her apartment! Hercule Poirot's Christmas A sadistic old man is brutally murdered in his locked study!
