    Special guests Ruta Sepetys and Steve Sheinkin join Tea, Tonic & Toxin to discuss their book The Bletchley Riddle.

    Remember, you are bound by the Official Secrets Act…

    Summer, 1940. Nineteen-year-old Jakob Novis and his quirky younger sister, Lizzie, share a love of riddles and puzzles. And now they’re living inside of one. The quarrelsome siblings find themselves amid one of the greatest secrets of World War II—Britain’s eccentric codebreaking factory at Bletchley Park. As Jakob joins Bletchley’s top minds to crack the Nazi’s Enigma cipher, fourteen-year-old Lizzie embarks on a mission to solve the mysterious disappearance of their mother.

    The Battle of Britain rages and Hitler’s invasion creeps closer. And at the same time, baffling messages and codes arrive on their doorstep while a menacing inspector lurks outside the gates of the Bletchley mansion. Are the messages truly for them, or are they a trap? Could the riddles of Enigma and their mother’s disappearance be somehow connected? Jakob and Lizzie must find a way to work together as they race to decipher clues that unravel a shocking puzzle that presents the ultimate challenge: How long must a secret be kept?

    Otto Penzler is president and CEO of MysteriousPress.com and proprietor of The Mysterious Bookshop in New York City. Long regarded as one of the world’s foremost authorities on crime, mystery, and suspense fiction, he has spent decades shaping the field as a publisher, editor, bookseller, and champion of both classic and contemporary crime writing.

    In 1975, Penzler founded The Mysterious Press, a publishing house that became one of the most respected names in mystery and suspense fiction. He sold the company to Warner Books in 1989, reacquired the imprint in 2010, and continued publishing literary crime fiction through Grove/Atlantic. Since January 2021, The Mysterious Press has again been independently owned. Through MysteriousPress.com, in partnership with Open Road Integrated Media, he publishes both original works and classic crime fiction.

    In fall 2018, Penzler established Penzler Publishers, which introduced American Mystery Classics, a line dedicated to bringing distinguished mystery and detective novels back into print, many after decades of unavailability. In September 2020, he launched Scarlet, an imprint devoted to psychological and domestic suspense. Charles Perry serves as publisher of all Penzler Publishers imprints, and Luisa Smith is editor-in-chief of Scarlet.

    Penzler’s contributions to the mystery world extend well beyond book publishing. For seventeen years, he published The Armchair Detective, the Edgar Award-winning quarterly journal devoted to the study of mystery and suspense fiction. He also created Otto Penzler Books and The Armchair Detective Library, fu

    Special guest Sergio Angelini joined Tea, Tonic & Toxin to discuss Christianna Brand’s Green for Danger, published in 1943.

    Green for Danger is a Golden Age masterclass of red herrings and twists. The story, set during World War II, features a tense and claustrophobic investigation with a close-knit circle of suspects.

    It’s 1942, and struggling up the hill to the new Kent military hospital, Heron’s Park, postman Joseph Higgins is soon to deliver seven acceptance letters for roles at the infirmary. He has no idea that the sender of one of the letters will be the cause of his death in just one year’s time.

    When Higgins returns to Heron’s Park with injuries from a bombing raid in 1943, his death by asphyxiation in the operating theatre casts four nurses and three doctors under suspicion. When a second death occurs in quick succession, the moody, yet shrewd, Inspector Cockrill arrives on the scene. The stage is set for a tense and claustrophobic investigation. One of the doct
