The adventure of Hemlock

In the smog-choked alleys of 17th-century London, Hemlock Barton Roger is hailed as the most brilliant mind on Earth, a detective who can read a man's sins from a single speck of ash. But beneath his cold, analytical genius lies a haunting vulnerability: Hemlock is desperate to prove he is more than just a calculating machine to a father who abandoned him as an unfeeling monster. When a series of impossible, occult-like murders sweeps through the royal courts, Hemlock is dragged into a global conspiracy that defies all rational logic. Armed only with his peerless intellect and a secret, forbidden notebook, he must hunt down an elusive shadow organization. As the investigations lead him across treacherous oceans and uncharted lands, Hemlock must rely on a fiery rogue scholar whose warmth threatens to melt his icy exterior, forcing him to choose between cold, hard facts and the terrifying chaos of human emotion.
