The Missing Koh-i-Noor

A Royal Jewel Disappears
During a royal visit to Chimneys, a famous jewel is replaced by an expert imitation and disappears. The loss is hushed up, leaving officials to search the house without knowing where Queen Varaga concealed the real stone.
A Secret Outlasts Its Keepers
King Victor is arrested in Paris soon afterward, but the jewel is never found. Its disappearance becomes a concealed national embarrassment and a possible motive for later searches at Chimneys.
A Coded Inheritance

The Count’s Knowledge
Count Stylptitch claims to know where the Koh-i-Noor is, and his memoirs may contain secrets capable of damaging powerful interests. His knowledge gives the manuscript importance beyond the political controversy already surrounding it.
A Chain of Clues
The old secret passes from Count Stylptitch’s world into the hands of Jimmy McGrath and Anthony Cade. The coded letters and the concealed jewel eventually prove to be connected through the same network of Queen Varaga and King Victor.
A Search in the Passage

The Cipher Is Decoded
A letter yields the cryptic instruction “Richmond Seven Straight Eight Left Three Right.” Virginia Revel recognizes the Earl of Richmond in the council chamber’s Holbein portrait as the clue’s starting point.
A Misleading Interpretation
The investigators calculate a route through the old passage and find a joke left by Count Stylptitch rather than the jewel. The false result proves that the clue has another layer and that the passage has recently been visited.
Rows and Roses

A Rose Disguised
Anthony Cade links the buttons, knitted square, and repeated letters in the passage to Count Stylptitch’s rose badge. The code points not to books but to a rose garden, where the directions can be measured from the sundial.
A New Search Ground
Hiram P. Fish has independently reached the garden clue. Anthony Cade recognizes that someone else understands the same code and begins watching his movements more closely.
The Garden Concealment

The Hidden Richmond Roses
Anthony Cade reveals that the Richmond code marks bushes in the rose garden, not a shelf in the library. A fake library solution draws the conspirators away from the real hiding place while the final confrontation unfolds.
Recovery After the Crisis
The diamond is recovered from the garden the next morning, restoring the missing jewel without publicizing the old royal scandal. Its return closes a secret that had survived revolution, disguise, and years of official silence.
