Monsieur Giraud

In the novel The Murder on the Links, Monsieur Giraud is a Detective of the Paris Sûreté and the investigating officer for Paul Renauld’s death. He considers Hercule Poirot to be his rival and resents his involvement in the investigation. He makes a bet with Poirot about who would arrest Renauld's murderer, and who did arrest them would receive 500 francs from the person who lost. Poirot got to the solution first and bought a dog decoration for his fireplace which he named Giraud.

Giraud worked with Monsieur Fournier, and told him about Poirot. (Death in the Clouds)

Portrayals
In the Agatha Christie's Poirot episode Murder on the Links, Monsieur Giraud was portrayed by Bill Moody. Here he is much more hostile towards Poirot than shown in the original novel. Other than that this portrayal strongly resembles the one in the original novel.

In Le crime ne paie pas, the France Télévisions and Escazal Films adaptation of the novel, the parallel character is Hubert Petitpont from the "police of the police".
