Blood Stone


All hell breaks loose when Detective Storm van der Merwe’s mom is pushed under a train at Paddington Station. Storm has to rush to London, even though she’s in the middle of a murder investigation: leading South African fashion designer Beebee Bukelwa Babu was found dead in a luxury Hermanus hotel.

Storm soon realises that her mom was a deliberate target. And she is one too. Meanwhile Storm’s former colleague, the bumbling Andreas Moerdyk, now a PI, is trying very hard to locate a missing and very valuable red diamond. From the murky streets of London to the diamond bourse in Antwerp, from secluded Port Nolloth to Storm’s beloved Hermanus, Irna van Zyl’s third crime novel unfolds at a heart-stopping pace.

Death Cup


When a notorious food blogger drops dead in a fancy Hermanus restaurant right in front of Detective Storm van der Merwe, Storm finds herself at the centre of a rotten mess: the blogger’s killer meal was laced with death cups, a mushroom more poisonous than even her most toxic restaurant review.

But sniffing out the murderer is not Storm’s only task: she has to put up former colleague Andreas Moerdyk when he quits his job, and to top it all her darling dog is missing.

Amid frantic preparations for a glitzy awards ceremony to honour the best chefs in the country, the killer strikes again – and again. Storm needs to act before yet another deadly dish is served.

Dead In The Water


Detective Storm van der Merwe is walking her dog on the beach when she makes a gruesome discovery: the body of a young journalist – missing a limb.

For the residents of Grootbaai, corpses are bad for business: thousands of tourists from all over the world flock to this coastal town to shark-cage dive with its famous great whites.

Storm is desperate to investigate the matter, but she’s been banished from the field to a dreary back office. She’s also carless after a tow-truck driver – an attractive one at that – crashed his truck into her Beetle.

Meanwhile, in Cape Town, Storm’s former colleague Andreas Moerdyk is having problems of his own while investigating the death of a famous Springbok rugby player whose car was also hit by a tow truck.

Is Storm’s car accident in some way related to the sports star’s fatal collision? And is there a link between the journalist’s death and stories of abalone poaching in Grootbaai?

As Storm searches for answers, she realises that everyone’s a suspect and the stakes are deadly.
