The Iron Tonic
The Iron Tonic: Or, A Winter Afternoon in Lonely Valley is a surrealist country-house mystery by Edward Gorey that presents a series of unresolved clues. The work features Gorey's characteristic fine-lined, 19th-century engraving style.
The work consists of 14 illustrated panels with accompanying rhyming text written in iambic pentameter. The narrative depicts a remote manor house inhabited by elderly and infirm residents.
The work is dedicated to the memory of Gorey's maternal great-grandmother, Helen St. John Garvey.
