A Thief in the Attic
Repeated intrusions
A mysterious intruder tries to reach Keeble’s plans and concealed work. Kraken identifies the man as Deener, a hireling connected to Drake.

Violence in a Lodging House
A staged encounter
Deener tricks Kraken with a woman’s disguise and attacks him with the peapot. He shoots at Kraken, whose book helps stop the bullet from killing him.
A warning ignored
The ambush leaves Kraken injured and separated from his livelihood. It shows that Drake’s agents will use deception and lethal violence to silence or control the people who know too much.
Sabotage and Abduction

Deener Strikes Again
Damage to the spacecraft
Deener enters St. Ives’s silo and damages the craft, helping cause its accidental launch. His destructive impulse harms the experiment even though he does not understand its workings.
A final attack
