Before I became a reviewer, and earned (I hope) the privilege of being sent books and .mobi files by publishers, I had been a lifetime library user. Crime Fiction was my first and last love, and in my regular Saturday afternoon trawl through the shelves, there were certain authors whose names I always sought out. In no particular order, these would include Jim Kelly, Phil Rickman, John Connolly, John Sandford, Val McDermid, Mark Billingham, Jonathan Kellerman, James Lee Burke, Graham Hurley, Christopher Fowler – and Graham Ison.

The Graham Ison books were slimmish-volumes, usually the Brock and Poole series, but my favourites were always the Hardcastle books. Ernie Hardcastle was a London copper in and around the years of The Great War. He could come over brusque in his dealings, but other might use the word ‘avuncular’. He distrusted innovations such as the telephone, but had a true copper’s nose for villains. A couple of his books are reviewed here, but inevitably, ‘time, like an ever-rolling stream, bears all its sons away..‘ Thankfully, in Hardcastle’s Secret Agent, Ernie is still with us, but long since retired, and the Hardcastle concerned is his son Walter, now a rising star in the Metropolitan Police.

HSAWe are, as ever, in London, but it is 1940. The Phony War is over, and the Luftwaffe are targetting industrial sites they believe to be involved in making parts for military aircraft. When several important employees of one such factory are burgled – clearly by an expert – but with nothing other than trinkets stolen, Hardcastle believes he may be on the track of a German spy on the look-out for plans, blueprints or important military information. Hardcastle has to deal with The Special Branch, but finds them about as co-operative as they were with his father a couple of decades earlier. This has a certain tinge of irony, as part of the author’s distinguished police career was spent as a Special Branch Operative.

The search for the German spy withers on the branch, but Hardcastle has other fish to fry. A prostitute – or at least, a young woman who was free with her favours –  has been found beaten to death, and the hunt for her killer takes Hardcastle into military quarters.

Eventually, Walter Hardcastle gets both of his men, and on the way we have a vividly recreated world of an England struggling to come to grips with a new world war. Not one that is being fought far away on some foreign field, but one which is brought to people’s very hearths and homes every single night. Hardcastle’s Secret Agent is published by Severn House/Canongate Books and will be out on 1st May.

Sad to relate, Graham Ison died suddenly in late 2020 before he could complete this book. It was finished with the help of his son Roger. Graham Ison was prolific, certainly, and critics might argue that he stuck to a reliable formula in each of his series, and never ventured into unfamiliar territory. Neither was he a darling of the crime fiction festival circuit, but I suspect after decades working as a policeman that never bothered him. What he was, however, was a reliable name for readers who bought his books and – importantly – library borrowers, who knew that they could rely on him for a story well told, and if his words took them into familiar territory, then that was nothing for either reader or writer to be ashamed about.
