Thaddeus Valentine Character Analysis

Thaddeus Valentine is the head of London’s Guild of Historians as well as the father of Katherine Valentine and possibly also Hester Shaw. Young Historian Tom Natsworthy idolizes Valentine, but in reality, Valentine holds several dark secrets. He murdered his former assistant and lover Pandora Shaw and seriously injured Hester, all to get his hands on a powerful weapon known as MEDUSA to take back to the Lord Mayor of London, Magnus Crome. Throughout the story, Valentine continues to resort to violence, killing Miss Fang and attempting to kill Tom. Valentine justifies his actions to himself by claiming that everything he does is for the benefit of his daughter, Katherine, but he’s forced to realize that this isn’t true when he ends up accidentally killing Katherine with his own sword. Unlike Crome, Valentine does have a conscience, but he follows it too late and ends up dying with the rest of London when MEDUSA malfunctions. Like Hester, Valentine shows how external appearances can be deceiving—in his case, showing how a person who appears to be kind and successful on the outside can actually be violent and ruthless on the inside.

Chapter 2 Quotes

Thaddeus Valentine was Tom’s hero: a former scavenger who had risen to become London’s most famous archaeologist—and also its Head Historian, much to the envy and disgust of people like Pomeroy. Tom kept a picture of him tacked to the dormitory wall above his bunk, and he had read his books, Adventures of a Practical Historian and America Deserta—Across the Dead Continent with Gun, Camera and Airship, until he knew them by heart.

And light burst down from above; the harsh beam of an airship’s searchlight raking across the snow. The aviatrix reeled blindly backwards, and Valentine leaped up, snatching his sword, pulling her hard against him as he drove it home. For a moment the two of them stumbled together like drunken dancers at the end of a party, close enough to Tom’s hiding place for him to see the bright blade push out through the back of Miss Fang’s neck and hear her desperate, choking whisper: “Hester Shaw will find you. She will find you and—”
