A truth drug … A secret uncovered … A desire for revenge … Who do we trust? Our loved ones, our friends, strangers? In a world where the truth is not always straightforward, scientists have tried time and again to engineer a drug that would compel people to reveal all. But is it always a good idea? Scientist and Police Consultant Dr Neroli Sonnclere is pulled into the middle of a great discovery—of a powerful new truth drug. It seems everyone sees the advantages in using it, but not always for the right reasons. Neroli soon realises that those close to her have hidden agendas. She learns that even the least likely of people have secrets, and that it’s incredibly easy to lie. And more importantly, that everyone, including her, is capable of betraying those we love. The third instalment of the SONNCLERE MYSTERY SERIES, THE EFFERVESCENCE OF TRUTH continues the adventures of a young female scientist with a unique gift. Born with hyperosmia, or a heightened sense of smell, Dr Sonnclere possesses the ability to sniff out odours undetected by ordinary humans. Together with Scotland Yard Detective Inspector Adam McClellan, Neroli recognises that others want to use the truth for their twisted plans. She uses her powerful nose and scientific knowledge to defend herself and keep the drug from falling into the wrong hands. The story uncovers intrigue within her University’s scientific community, the questionable ethics of the British media, and reveals that all is not well at the heart of London’s Russian high society. Is the truth so important? The reality is—truth can be dangerous. Would you want the truth even if it may hurt in the end?
