We will suppose first that some person or persons inside the house did the crime. They got this man down here at a time when everything was still and yet no one was asleep. They then did the deed with the queerest and noisiest weapon in the world so as to tell everyone what had happened--a weapon that was never seen in the house before. That does not seem a very likely start, does it?
我們先假定是莊園內部的一個或幾個人作案。在萬籟俱寂、但人們還沒就寢的時候，他們在這裏抓到了這個道格拉斯，然後用這種世上最古怪而聲音最響的武器去作案，以便搞得盡人皆知發生了什麽事，而武器又是莊園內從沒見過的。這個理由看來不是那麽令人信服，對嗎？
