The biggest heist in history has left behind a trail of crimes. The investigation has uncovered four criminals behind the operation: a traitor, a fraudster, a thief and a killer. The problem? They’ve disappeared into a sea of names.

The manhunt begins with a stolen priceless treasure. But the robbery is only part of the story. A TRAITOR betrayed their colleagues and leaked confidential information. A professional FRAUDSTER created a web of fake identities, forged records and false transactions to cover their tracks. A master THIEF carried out the theft itself. And when the operation threatened to unravel, a KILLER stepped in to silence the one person who could expose them all.

As the lead investigator, it’s your reputation on the line to solve the case. When you receive an email out of the blue with the subject line, ‘Catch us if you can’, you think it’s a prank. But the four criminals have sent you a list of names in four separate case files, with 12 clues to try to catch each member of the criminal gang.

Your mission is to track them down. Follow the clues, eliminate the innocent and identify the criminals hiding in plain sight. With four interconnected investigations with 40,000 names to search, The Killer Isn't Alone is a unique test of deduction, logic and observation. Can you catch them all?
