The Black Circle is the fifth book of the The 39 Clues, written by Patrick Carman.


The book starts with Amy and Dan Cahill getting a telegram at midnight. Fearing for their lives, they quickly changed hotels. The telegram told them to go to a locker in the airport, but to come alone. They leave Nellie a note and leave.

They are closely followed by Hamilton Holt. In the airport, they lose him, but then run into Ian and Natalie Kabra. Dan makes a run for it but Ian grabs Amy quickly. She kicks him in the leg extremely hard. They make it to the locker in time to discover objects in a box left by a mysterious person going by the initials NRR. In the box there is a guidebook, disguises, passports, a snow globe, a credit card, a note with seemingly random letters on it, and a photo of their parents outside the Russian Embassy. Dan and Amy unscramble the letters and find out that the next Clue(s) are in the following Russian cities: Volgograd, Moscow, Yekaterinburg, and St. Petersburg. They board their plane quickly without Nellie and Saladin.

Then they both fly to Russia, ending up in Volgograd. Here they meet and work with the Holts, climbing the inside of The Motherland Calls to discover a hint to the Clue around Rasputin, Anastasia, and Alexei. They check out the cities on the list they found by the eye of the statue, buying a car in the process, leading them to the place Rasputin died.

During an attack by the Kabras, the Holts alert them of a location code which guides them to a Lucian base, the Kremlin. There, they discover who the mysterious NRR is; Nataliya Ruslanovna Radova, Anastasia's only daughter. They also find the Clue in the Amber Room in the St. Petersburg Cathedral which has been given Black Circle clearance, meaning that only Lucians given permission directly from Vikram Kabra can enter.

They then find the Clue, a half gram of melted amber, and as Irina Spasky catches them, The Man in Black bursts in, attacks Irina and the other Lucians, indirectly saving the duo. They call the Holts and tell them what the next Clue is, only for Eisenhower to call their alliance off.

In the audiobook, there is an audio extra featuring a phone conversation between Grace Cahill and Anastasia Romanov.

Re: New strategy

My esteemed fellow Lucians,

The hunt for the 39 Clues has proved more complicated than expected. It's time to make the other Cahill branches feel the full force of Lucian power, even if it gets a little...messy. I am sending all agents into the field to join the hunt, and I authorize you to use whatever means neccessary to find the Clues. Any "accidents" involving rival Cahills will be overlooked. Just get the job done.
