Jocelyn McClurg of "USA Today" gave the book three out of four stars, saying that “channeling Dickens, Belfoure designs a rollicking story but overloads on improbabilities. No matter – it’s a blueprint for great fun”. "House of Thieves" was said to be adapted for television by the Mark Gordon Company, with Francis Lawrence to direct the series. Belfoure's third novel, "The Fallen Architect", was released on October 9, 2018. Set in 1905, it tells the story of a British architect in the Edwardian era. "Publishers Weekly" reviewer called it an “exceptional mystery” and said that “Belfoure offers the reader glimpses of early motion pictures, variety hall jokes that are still funny, and a description of Edward VII consuming a 10-course meal. This wonderfully realized background coupled with insights into British society make this a standout”, yet "Kirkus Reviews" contributor pointed out that several “structural failures loom” in the course of the plot, and one of the plot twists “is a cul de sac from which Belfoure, himself an architect, cannot design a convincing exit. The music hall décor and atmosphere help distract from the flawed whodunit”. "The Fallen Architect" was announced a 2019 Nero Award Finalist. In 2018, Belfoure announced that he has been working on his fourth novel. "The Fabergé Secret", set to be released by Severn House of London on January 5, 2021 in the U.K. and the U.S., takes place in the world of the Russian Imperial Court of Nicholas and Alexandra. It is about a Russian prince whose life is changed after he witnesses the 1903 Easter Sunday pogrom in Kishinev. Belfoure uses his architectural background to develop the plot of his novels. He said that he never took creative writing lessons and that he “hesitated writing fiction”, but discovered that John Grisham, who was also never trained in writing, has been using his legal background for his fiction works. Belfoure decided to use his knowledge in the field of architecture in a similar way. When aksed about the works that influenced him most, he pointed to Robert Moses' "The Power Broker", William Golding's "Lord of the Flies" and novels by Thomas Hardy, especially "Jude the Obscure" and "The Mayor of Casterbridge".
