A legendary black diamond known as The Black Falcon disappears during a high-profile private auction in Dubai. Worth hundreds of millions of dollars, the diamond is believed to contain a hidden secret that could expose the powerful and mysterious Falcon Circle-a criminal organization that has operated in the shadows for centuries.
When Sarah Khan, Ayesha Khan, and Ali Khan are hired to investigate, they find themselves caught in a deadly international conspiracy involving wealthy collectors, secret agents, art smugglers, and corrupt insiders. As clues lead them from Dubai to Istanbul, London, and Zurich, the siblings discover that someone within the Falcon Circle has been expecting them.
With danger around every corner, Sarah must rely on her intelligence, Ayesha on her courage, and Ali on his technology skills-and sense of humor-to survive their most challenging case yet.
Filled with adventure, mystery, suspense, unexpected twists, and the hilarious sibling chemistry readers love, The Shadow of the Black Falcon is an unforgettable journey where trust is dangerous, secrets are deadly, and nothing is as it seems.
One Missing Diamond.
One Ancient Secret.
One Global Conspiracy.
And three detectives who refuse to quit.
