Story Introduction

After his concert on Saturday, April 4th, 2026, at the PSD Dome in Düsseldorf, Alec Wren disappeared.

The next morning, he and his wife Kova were supposed to get on the tour bus at 10:00 a.m. for the next stop. But they never showed up.

Kova had tried to call a friend the night before, but the call was suddenly interrupted. During the call, strange knocking sounds could be heard in the background, almost like a secret code. Later, investigators discovered a plane ticket, a mysterious note, and a strange phone number.

So far, two concerts have had to be cancelled.

This case is strictly confidential and of the highest priority.

Once again, Sherlock Holmes and Dr. Watson have been called to investigate. They have identified five suspects. But they cannot solve the case alone.

After your success in the last case, they are now asking for your help.

Follow the clues. Solve the riddles. Find out what happened. And find out:

Who took Alec?
