MP Arthur Gill is one of Westminster’s rising stars. Still in his 30s, he’s just become the Secretary of State for Justice, assuming the role of Lord Chancellor too; and with a leadership race on the horizon, he’s a favourite to be the next Prime Minister. But there’s a problem. An inquiry headed by Lady Justice Deborah Wingate is on the brink of publishing its findings about a public health disaster: a scandal that happened on Gill’s watch when he was environment minister. As leaks multiply and the waters grow murkier, how far will he go to hide his past and protect his future? The Inquiry is a gripping drama about the pernicious collision between politics, justice and ambition.
