Praise For The Series
⭐️⭐️⭐️⭐️⭐️ The Shadow Over the Seine Stayed With Me🎶🔰 ⭐️⭐️⭐️⭐️⭐️
The Shadow Over the Seine Stayed With Me is the best way I can describe my experience with this novel. It feels like discovering a forgotten Sherlock Holmes adventure that had been tucked away for years, waiting for the right reader to find it. The letter format gives the story a fresh perspective while still sounding true to the world of Holmes and Watson.
The mystery unfolds at a steady pace, revealing just enough to keep curiosity alive without rushing to the next twist. Paris provides a wonderful backdrop, adding atmosphere without overshadowing the investigation itself. The descriptions are vivid enough to picture every street, café, and quiet conversation, yet they never slow the story down...

⭐️⭐️⭐️⭐️⭐️ An atmospheric and intriguing Sherlock Holmes mystery⭐️⭐️⭐️⭐️⭐️
A fascinating mystery with a strong historical atmosphere. I especially enjoyed the unusual format of the story being revealed through Holmes’s letters to Watson. It gives the book a personal feeling while gradually building suspense.
The setting in Rome and the Vatican works very well, especially with the secret archives, hidden connections, mysterious documents, and questions about who can really be trusted. The investigation develops slowly but keeps adding new layers, and Holmes’s careful observations and logical approach remain at the center of the story.
A good choice for readers who enjoy Sherlock Holmes, historical mysteries, secret societies, and stories built around old documents and hidden truths.

⭐️⭐️⭐️⭐️⭐️The Majestic Becomes a World of Its Own.⭐️⭐️⭐️⭐️⭐️
The Majestic becomes a world of its own as Sherlock Holmes secretly follows Sebastian Moran across the Atlantic. Holmes moves between elegant first-class rooms and the crowded lower decks, using disguises and careful observation while trying to recover a dangerous document. The contrast between the passengers, especially during the storm, gives the story more depth than a simple chase...

SAINT PETER’S CONFESSION
Sherlock Holmes: The Secret Letters Book 2
Rome, 1891.
In the shadow of St. Peter’s Basilica, a sacred painting has been quietly replaced—its absence unnoticed, its significance unknown.
Summoned into the heart of the Vatican, Sherlock Holmes is confronted with a mystery that is not merely criminal, but deeply historical. Behind the missing artwork lies a hidden document—one that may alter the understanding of faith, power, and the fragile balance upon which institutions are built.
As Holmes navigates a world of guarded archives, silent corridors, and carefully controlled access, he encounters figures who speak in half-truths and act with concealed intent. In Rome, nothing is freely given—every answer must be earned.
Holmes is drawn into a web of secrecy that stretches beyond the Vatican walls. And as the truth begins to surface, it becomes increasingly unclear whether it is meant to be revealed at all.
Saint Peter’s Confession is a new Sherlock Holmes mystery—where history, belief, and deception converge, and where the greatest danger may lie not in what is hidden, but in what is uncovered.
