The fourth book in the cycle “The Investigation Is Led by Her Majesty” takes the reader to 1957, a time when the young Queen Elizabeth II is learning the difficult craft of presenting the British monarchy on the world stage. Every trip abroad becomes a test of endurance and self-control. And especially so when, on the eve of an important public address, a pre-written text of her speech disappears under mysterious circumstances.
At the same time, in London’s Chelsea, a double murder is committed: an escort girl is found dead with a diamond tiara on her head, while her companion is strangled, with a knife embedded in his eye. The investigation stalls—apparently, someone is deliberately interfering with the police. Elizabeth II begins to suspect that a person from her inner circle may be involved. Will the Queen and her loyal assistant, Joan McGrou, manage to unravel this dangerous tangle?
