The Formula Becomes a Target

The Formula Becomes a Target
A valuable secret
Eberhard’s formula promises a major improvement in steel strength and aircraft design. Its potential commercial and military value makes the government meeting at Wyvern Abbey an obvious target.
Suspicion spreads
The Seven Dials meeting discusses the formula and the arrival of key guests. The audience is led to expect a theft by an international criminal group, establishing the apparent conflict that Jimmy Thesiger will exploit.
A Watch Arranged

A Watch Arranged
Guardians assigned
Jimmy Thesiger and William Eversleigh divide the night into watches to protect Sir Stanley Digby and the formula. Bundle Brent is explicitly excluded from the plan.
A vulnerability created
The arrangement gives Jimmy Thesiger a legitimate reason to be near the documents and a way to control who is watching. The apparent security plan becomes part of the conditions for staging the theft.
The Library Struggle

The Library Struggle
Gunfire and confusion
The household hears a crash and two shots from the library. Jimmy Thesiger is found wounded beside a pistol, while Terence O'Rourke is drugged and the papers are missing.
A convincing crime scene
The chaos makes it appear that an intruder fought with Jimmy Thesiger and escaped with the formula. The staged event directs attention outward and leaves the household too alarmed to examine the performance closely.
Loraine’s Packet

Loraine’s Packet
A witness appears
Loraine Wade arrives with a parcel and says she saw a man climb down the ivy. The package contains the papers, and she is praised for recovering them.
Relief masks questions
The return of the formula reassures the officials, but the delivery is too convenient to settle the case. Superintendent Battle notices that the parcel may have been thrown deliberately to the person expected below.
The Performance Reconstructed

The Performance Reconstructed
No outside attacker
Superintendent Battle explains that Jimmy Thesiger staged the fight, left the library by the window, retrieved the formula, and returned to manufacture the apparent escape. Loraine Wade’s presence was part of the plan.
Crime exposed through detail
The glove, the pistol’s distance, and the implausible timing expose the theft as a performance. What seemed like a thwarted robbery was actually a carefully arranged attempt to control evidence and eliminate witnesses.
