Note: Title translates as "Captain Spéirling Again"

Synopsis: "Captain Spéirling and Professor Ó Glarcáin are sent to Venus to bring back Ross Simms, an English space-pilot who has travelled to Venus without authorisation, and subsequently disappeared. Upon arriving on Venus, the two Irishmen discover that Simms has married the Venusian Queen, Ena, and that he is helping her to launch an assault on Earth. Spéirling and Ó Glarcáin are sent to the Venusian marshes as slaves; ten days later, they manage to escape, end slavery and oversee the transition to a more just and equal Venus. Simms, driven mad by a Venusian prophet who tells him he will die in seven days, attempts to escape from Venus and ends up crashing his ship into the Sun. All's well that ends well, and the two Irishmen return home to planet Earth, where nobody will ever realise the danger our world was in." —Jack Fennell
