It is Halloween in King's Lynn, and forensic archaeologist Dr Ruth Galloway is attending a strange event at the local history museum - the opening of a coffin containing the bones of a medieval bishop. But then Ruth finds the body of the museum's curator lying beside the coffin.

Soon the museum's wealthy owner lies dead in his stables too. These two deaths could be from natural causes but DCI Harry Nelson isn't convinced, and it is only a matter of time before Ruth and Nelson cross paths once more.

When threatening letters come to light, events take an even more sinister turn. But as Ruth's friends become involved, where will her loyalties lie? As her convictions are tested, she and Nelson must discover how Aboriginal skulls, drug smuggling and the Aboriginal ritual of The Dreaming may hold the answer to these deaths - and be the key to their own survival.

The murder of women priests in Norfolk's spooky shrine town of Walsingham draws forensic archaeologist Dr Ruth Galloway into a thrilling new adventure.

When Ruth's friend Cathbad sees a vision of the Virgin Mary, in a white gown and blue cloak, in Walsingham's graveyard, he takes it in his stride. Walsingham has strong connections to Mary, and Cathbad is a druid after all; visions come with the job. But when the body of a woman in a blue dressing-gown is found dead the next day in a nearby ditch, it is clear that a horrible crime has been committed, and DCI Nelson and his team are called in for what is now a murder investigation.

Ruth, a devout atheist, has managed to avoid Walsingham during her seventeen years in Norfolk. But then an old university friend asks to meet her in the village, and Ruth is amazed to discover that she is now a priest. She has been receiving vitriolic anonymous letters targeting women priests - letters containing references to local archaeology and a striking phrase about a woman 'clad in blue, weeping for the world'.

Then another woman is murdered - a priest. As Walsingham prepares for its annual Easter re-enactment of the Crucifixion, the race is on to unmask the killer before they strike again...

Boiled human bones have been found in Norwich's web of underground tunnels. When Dr Ruth Galloway discovers they were recently buried, DCI Nelson has a murder inquiry on his hands. The boiling might have been just a medieval curiosity - now it suggests a much more sinister purpose.

Meanwhile, DS Judy Johnson is investigating the disappearance of a local rough sleeper. The only trace of her is the rumour that she's gone 'underground'. This might be a figure of speech, but with the discovery of the bones and the rumours both Ruth and the police have heard that the network of old chalk-mining tunnels under Norwich is home to a vast community of rough sleepers, the clues point in only one direction. Local academic Martin Kellerman knows all about the tunnels and their history - but can his assertions of cannibalism and ritual killing possibly be true?

As the weather gets hotter, tensions rise. A local woman goes missing and the police are under attack. Ruth and Nelson must unravel the dark secrets of The Underground and discover just what gruesome secrets lurk at its heart - before it claims another victim.

'Recalls the very best of Agatha Christie' Sunday Express

Brighton, 1951. Pantomime season takes a dark turn when two missing children are found dead under the snow, surrounded by sweets - a macabre, real-life Hansel and Gretel.

DI Edgar Stephens has plenty of leads to investigate. The missing girl, Annie, used to write plays and perform them with her friends. Does the clue lie in Annie's unfinished - and rather disturbing - last script? Or might it lie with the eccentric actor types who have assembled for the pantomime?

Once again Edgar enlists magician and ex-wartime comrade Max Mephisto's help in penetrating the shadowy theatrical world that seems to hold the key. But is this all just classic misdirection?

On the eve of the Queen's coronation, DI Stephens and Max Mephisto uncover an anarchist plot and a ticking bomb - from the author of The Stranger Diaries and the Dr Ruth Galloway mysteries.

Elizabeth II's coronation is looming, but the murder of their wartime commander, Colonel Cartwright, spoils the happy mood for DI Edgar Stephens and magician Max Mephisto. A playbill featuring another deceased comrade is found in Colonel Cartwright's possession, and a playing card, the ace of hearts: the blood card. The wartime connection and the suggestion of magic are for Stephens and Mephisto to be summoned to the case.

Edgar's ongoing investigation into the death of Brighton fortune-teller Madame Zabini is put on hold. Max is busy rehearsing for a spectacular Coronation Day variety show - and his television debut - so it's Edgar who is sent to New York, a land of plenty worlds away from still-rationed England. He's on the trail of a small-town mesmerist who may provide the key, but someone silences him first. It's Edgar's colleague, DS Emma Holmes, who finds the clue, buried in the files of the Zabini case, that leads them to an anarchist group intent on providing an explosive finale to Coronation Day.

Now it's up to Edgar, Max and Emma to foil the plot, and find out who it is who's been dealing the cards . . .

What do a murdered Brighton flower seller, the death of Cleopatra and a nude tableau show have in common? Read the most dangerous case yet for Stephens and Mephisto to find out.

Christmas 1953. Max Mephisto and his daughter Ruby are headlining Brighton Hippodrome, an achievement only slightly marred by the less-than-savoury support act: a tableau show of naked 'living statues'. This might appear to have nothing in common with DI Edgar Stephens' current case of the death of a quiet flowerseller, but if there's one thing the old comrades have learned it's that, in Brighton, the line between art and life - and death - is all too easily blurred...
