## Key lines

> Admirable, mon ami, admirable! Up where, and at whom? Be precise, I beg of you.

Poirot sarcastically praises Hastings' enthusiasm but asks for specific details about his plan.

_Poirot's characteristic use of French and his demand for precision._

> Will you walk into my parlour, said the spider to the fly?

Poirot compares the dropped pocketbook to a trap set by the Big Four.

_Reference to the nursery rhyme, indicating Poirot's awareness of the deception._
