Page "Mortal Engines" Paragraph 16

While they drift away on the wind, Hester tells Tom that she used to know Shrike.

He found her half-dead after her parents ' murder, when she was abandoned in the Great Hunting Ground, and he raised her.

When she found out who Valentine was, and swore revenge, Shrike forbade her from going.

So she ran away from him, and when she finally did find Valentine Tom thwarted her assassination attempt.

However, she has no idea why Shrike was on a mission from the Lord Mayor of London.
