Books in all three of Bellairs’ young-adult series have been released by publishers in the United Kingdom.

The first and third titles in the Lewis Barnavelt series were published by Hutchinson (House in 1978 and Letter in 1980); we’re not clear as to why they skipped over The Figure in the Shadows. Hutchinson also published The Treasure of Alpheus Winterborn (1982). Letter and Treasure used the same artwork seen on their American counterparts; House used a colorized version of Gorey’s frontispiece.

Corgi published the first three books in the Johnny Dixon series as paperbacks during the late 1980s. Cover art was created by illustrator Steve Lavis.
