One Mysterious Knife?

Finally, the knife ends up in police custody!

In her novel The Murder on the Links, Agatha Christie describes the murder weapon as having a plain black handle. In the Agatha Christie's Poirot adaptation, it sports an elegant golden handle. In her novel, it's referred to as a knife, a letter opener, or a dagger. Jack Renauld had it made to commemorate his military service in World War I. He was a pilot, and although it's never stated, we wonder if some of the metal came from the wreckage of his crashed plane.

The knife in Agatha Christie's novel may not be as pretty as its TV cousin, but it's more mysterious. Finally, we learn the reason for its amazing mobility. Jack Renauld commissioned not just one knife, but three. He gave one to his mother, one to Ms. Duveen, and one to Marthe Daubreil. So which knife committed which murder? 

I wonder how many former soldiers like Jack Renauld commissioned weapons to commemorate their World War I service.
