Sherlock Holmes and the Scandal of the Portuguese Bank

A forgotten fraud. A legendary detective. A final enigma. One of the boldest financial crimes in history resurfaces in a dazzling new literary investigation. Sherlock Holmes and the Scandal of the Portuguese Bank, authored by Richard H. Cross, casts the iconic detective into the shadows of 1925 Lisbon, where forged signatures, millions of genuine banknotes, and an elusive criminal mastermind converge.

Blending real historical events with the suspenseful style of Arthur Conan Doyle, this novel marks the start of a thrilling new saga: The Congregation Cycle. At the centre is Alves dos Reis, a man who nearly brought down a nation—and who may not have acted alone. As Holmes and Watson trace the contours of a conspiracy that spans continents, readers are drawn into a world where politics, finance and justice clash with the methods of reason.

With a foreword by Professor Guido Pagapini (University of Bath) and a narrative faithful to Watson’s voice, the novel is both homage and revelation. A must-read for fans of classic detective fiction, historical thrillers and economic intrigue.

Truth lies buried beneath layers of banknotes.
But Holmes still has his magnifying glass—
and the world, one final mystery to solve.
