Hastings, Japp and others in “Unfinished Business”

Hastings

Where is Mrs. Japp tonight then?

She can't abide fireworks.

Poirot

Ah, the noise disturbs the delicate sensibilities of many ladies.

Maybe, maybe. I think it's more that she doesn't like to see people enjoying themselves.

Hastings

Tell you what though, what a good night for a murder, eh? I mean, if somebody wanted to kill anybody, nobody would know if it was a gunshot or a firework.

Poirot

But not so good, my friend, if your chosen method is strangulation.

Hastings

No. That's true, no.

Or poisoning, come to that.
