The Four Voice Cipher

By Richard Sharp

Three thousand years ago, someone carved a musical chord into an Egyptian stone. It should have remained silent forever. A year after his wife's death, mathematician Daniel Reis has learned to survive by trusting only what can be proved. Numbers. Equations. Then, in the basement of a museum in Turin, he finds something that should be impossible.
An ancient Egyptian stela engraved with a musical chord.

The same chord, note for note, that his wife was playing before she died - carved in stone three thousand years before she was born. Daniel needs to know how. But someone else needs to make sure he never finds out. His search draws him into a trail concealed across centuries, hidden in music, mathematics, ancient monuments and fragments of history that were never meant to fit together. And Daniel is not the first to follow it.

Hunted from Turin to Rome, from Prague to the Egyptian desert, Daniel is pulled deeper into a mystery guarded for generations - and towards a discovery that could challenge everything we think we know about consciousness, death and the boundary between science and faith.

But the closer he gets to the truth, the more personal the mystery becomes. Because Daniel's wife left behind one thing he has never been able to explain. An unfinished musical phrase. A phrase that should have ended. A phrase that didn't.

What if it was never unfinished?
What if she had already found the final note?
And what if finding it means discovering that death is not where the story ends?

The Four Voice Cipher is a fast-paced conspiracy thriller of ancient secrets, forbidden knowledge, mathematics, music and historical mystery - for readers who love puzzles buried in history, dangerous discoveries and mysteries that make the impossible feel just one step away from being true.

Three thousand years of silence.
One unfinished phrase.
One question no equation can answer.

Some secrets are buried to keep them hidden. Others are buried because someone is waiting for them to be found.
