The Marx Sisters

First published : 1994 Hamish Hamilton/Penguin, UK; 1999 Arcade, USA

Jerusalem Lane is a little piece of Dickensian London untouched by development, its inhabitants mainly refugees from pre-war central Europe. But could elderly Meredith Winterbottom really have been killed for the politics of another age?

As DS Kolla and DCI Brock delve into the Lane’s eccentric melting pot, past and present interlink in unexpected ways. What connects Mrs Rosenfeldt and Adam Kowalski to a smooth property developer and an American academic? And what is Meredith’s son Terry up to? Not to mention the dottily Marxist sisters. Could this be a recipe for murder?

The Malcontenta

First published : 1995 Hamish Hamilton/Penguin, UK; 2000 Arcade, USA

For DS Kathy Kolla the chance to investigate the unnatural death of a physio at the exclusive Stanhope House Clinic seems the ideal opportunity to leave behind more mundane police duties. Especially when what at first seemed suicide or accidental death is clearly more complicated. A cover-up to shield the clinic’s illustrious clients, or murder?

So Kolla is not at all pleased when she is abruptly taken off the case, and turns to DCI Brock for help. But their unofficial inquiries flounder in the mire of corruption as the violence behind the clinic’s respectable face escalates out of control.

All My Enemies

First published : 1996 Hamish Hamilton/Penguin, UK

The phone call comes on a Sunday, the day before homicide detective Kathy Kolla is to start her new job at New Scotland Yard, Serious Crimes Branch. But the grotesque murder that it heralds in a peaceful London suburb takes no account of the day of rest and promises a dramatic start to Kathy’s new life.

In fact, dramatic is the word when her only – improbable – lead draws her to an amateur drama group. As Kathy investigates further she is lured into a piece of theatre over which, increasingly, she has little control. And as the show unfolds, a plot of brilliant complexity is revealed, escalating with gathering suspense to a climax in which Kathy’s own painfully hidden past plays a shocking role.

As this investigation proceeds, Brock is now the one under suspicion. His team is disbanded and DS Kathy Kolla is unwillingly reassigned.

Silvermeadow, the glossy, huge new shopping mall on the outskirts of London, is not what it seems.

Dark Mirror

First published : 2009 Allen & Unwin, Australia

In the tenth Brock and Kolla mystery, Marion Summers – red-haired, beautiful and mysterious – collapses and dies in the rarified surroundings of the London Library. When DI Kathy Kolla and DCI David Brock investigate, Kathy finds a reluctant kinship with the victim, who, like Kathy, left a difficult home life when young and struck out to London for independence.

Marion’s research on the intriguing, adulterous circle of artists, wives, lovers and muses around Victorian artist Dante Gabriel Rossetti seems irrelevant, until the use of arsenic arises. As Brock and Kolla get closer to the truth, another victim dies an excrutiating death in a library, and it looks like a serial poisoner is on the loose.

Chelsea Mansions

The mystery begins at the Chelsea Flower Show in London, where two American tourists are stalked by a killer…

Following Perestroika, vast fortunes were made from the rapid privatisation of Russian state assets by sharp entrepreneurs. When Vladimir Putin came to power and wanted to recover these funds, many of the new billionaires fled to the West, and in particular to London, where generous tax breaks and a reluctance to extradite the oligarchs to their homeland offered a comfortable sanctuary. This is the background to DCI Brock and DI Kolla’s latest investigation, in which the multi-millionaire Mikhail Moszynski, with his new Caribbean model wife Shaka and a colourful Russian entourage, has created a glitzy palace in Chelsea Mansions, a grand Victorian residential block in one of London’s golden postcodes, to the discomfort of the locals.

The Raven’s Eye

First published : 2013 Allen & Unwin, Australia; 2013 St Martin’s Press / Minotaur

A woman dies in her sleep in a houseboat on the Thames; the apparent cause of death, an unflued gas heater. It all seems straightforward, but DI Kathy Kolla isn’t convinced.

Unfortunately both Kathy and DCI Brock are up against an aggressive new Commander who seems to have a different agenda, opposing their investigation in favour of emerging technologies over the traditional policing methods. Coppers like Brock and Kolla who have reservations are being squeezed out.

Detective Sergeant Harry Belltree has a new posting. Away from Sydney, where he was nearly killed by a corrupt colleague and is now an embarrassment. Off to a quiet life in Newcastle.

Or maybe not so quiet. A body’s been dug up on Ash Island. It may not be the only one.
