Hakim and Arnold Books in Order

The Hakim and Arnold books begin with a small detective agency in East London and two people who, on paper, should not be an obvious team. Lee Arnold is a former soldier and ex-policeman trying to keep his investigation business afloat. Mumtaz Hakim is a Muslim widow with a background in psychology who joins him as an assistant and quickly proves she is much more than that. From A Private Business onward, the series turns on the tension, trust, and gradual respect between those two very different minds.

What makes these books work is the kind of cases they take. Arnold and Hakim are not moving in glamorous private-eye circles. Their clients are often vulnerable, frightened, or short of options. A woman worries that her husband is hiding something. A family searches for a missing child. Someone comes back from the dead, or seems to. A local mystery opens into something much uglier. Again and again, the agency ends up dealing with the people official systems have missed, ignored, or written off.

The East End is not wallpaper.

Nadel uses modern East London as a living, changing landscape. Stratford, East Ham, Barking, Shoreditch, and the streets around them are full of pressure, redevelopment, poverty, old loyalties, new money, crime, religion, and community politics. In books like An Act of Kindness, Poisoned Ground, and Enough Rope, the investigations move through Bangladeshi households, back streets, housing estates, tunnels, graveyards, and half-gentrified neighborhoods where one world sits right on top of another. The setting matters because the crimes grow out of it.

Mumtaz becomes the emotional center of the series for many readers. She is observant, practical, and far tougher than some people first assume. Her faith is part of her life, but so are money worries, family pressure, and the long shadow left by her late husband’s debts and criminal connections. Lee, meanwhile, is not presented as a neat hero. He is older, bruised by experience, sometimes secretive, sometimes stubborn, and often forced to admit that Mumtaz sees things he does not.

That gives the books a grounded, human rhythm. The mysteries are there, and they are often dark, but the series is just as interested in how people live in a crowded city when cultures overlap, social rules clash, and danger can arrive through family, ideology, money, or simple bad luck. Later novels such as Bright Shiny Things, Web of Lies, and The East Ham Golem widen the scale, bringing in terrorism, buried history, and old myths, but the heart of the series stays the same.

These are private-investigator novels with a strong social pulse. They are tense, streetwise, and often sad, but never cold. If you like crime fiction where the detectives have to navigate not just clues but whole communities, Hakim and Arnold is a very good place to start.
