A highly valuable painting of dahlias by Henri Fantin-Latour has been stolen, and Allmen International Inquiries is commissioned to take on the investigation. This is most definitely a case for private investigator Johann Friedrich von Allmen, his assistant Carlos and his captivating life partner María Moreno, who has been enhancing the duo of late – and no less juicy than the two previous cases. The picture was already stolen property before it exchanged unrightful owners. And the old lady in whose possession it was until recently – Dalia Gutbauer, a very rich heiress and owner of a now slightly run-down luxury hotel – has enough money to simply buy a new Fantin-Latour without making a dent in her fortune. So why is she so attached to the picture? It takes Allmen a long time to see the slippery surface he is investigating, dealing with shady crooks as well as his own kind: experts in not having any money, with more demands than means. But there is one thing which is even more dangerous: aging men with young women.

Now things are getting serious: Allmen's International Enquiries has its first major case: An incredibly valuable pink diamond has disappeared, along with a mysterious Russian living in Switzerland and suspected of having stolen it. It is up to Allmen and Carlos to track him down. The trail leads them from London via the run-down outskirts of Zurich to a grand hotel in the German Baltic Sea resort of Heiligendamm, then back to the garden house in the Schwarzacker Villa in Zurich where things are about to get very awkward . . . A case in which nothing is as it seems, and one of global interest. The Allmen and Carlos duo have to prove just how much they are able to master the art of confidence trickery and understatement – and are up against the professionals.

The Allmen series – over one million copies sold!

The bestselling crime novel series about the gentleman crook Allmen and his assistant Carlos has sold over a million copies in German alone and was first adapted for TV in 2017 by UFA fiction.

In the sixth episode of the stylish series Allmen’s International Enquiries investigates on Ibiza, the Mediterranean island of the super-rich.

An anonymous invitation lures Allmen to an exclusive property in Ibiza. An old man awaits him by a large pond and shows him his valuable many koi. One of the trusting fish – the most valuable one – has disappeared.
Allmen’s International Enquiries receives the brief of finding ›Boy‹, worth almost a million Euro. Allmen and his crew find a way of discreetly accessing the exclusive world of the island’s high society, and gain insight into a peculiar passion for collecting. 

Allmen meets a cultured gentleman of around his age in a bar – Adrian Weynfeldt. His family name, of course, is one the art detective is familiar with. Their encounter marks the beginning of an unusual friendship. A short while later, when Weynfeldt notices a picture is missing from his collection, he consults Allmen. Weynfeldt’s eccentric circle of friends seems reluctant to talk, all except the bookseller who specialises in art titles. But before long, she’s no longer able to, and Allmen is facing his first murder case.

Jonas Brand has no idea about the adventure that awaits him, when the intercity train comes to an abrupt halt. The train is unable to continue because of a dead body on the tracks. Brand immediately shoulders his camera, records the nightmarish events and interviews his fellow passengers. He is a freelance journalist, but one who dreams of bigger things. He wants to make films, and his project ›Montecristo‹, a story of betrayal, deception and late revenge, has blockbuster potential – if only someone would give him a chance. When he falls in love with Marina Ruiz, who charms him into revealing his dream, the project steps back into his focus. Just three months later, fate deals him another bizarre card: two onehundred Swiss Franc notes with identical serial numbers – both of which, as the bank confirms with amazement, are genuine. Then Brand’s apartment is ransacked and he gets beaten up and robbed in broad daylight. Someone clearly wants to throw him off the track that he is just about to embark on.

Johann Friedrich von Allmen, elegant gentleman, playboy and art collector, has managed over the years to blow the millions he inherited from his father. After selling off his grand estate, he moves into the modest gardener's residence with his worldly-wise Guatemalan factotum Carlos. He is as expert in his dealings with debts and creditors as he is bad with money. Then, after a tipsy night at the opera, a voracious young woman called Jojo drags him off to her father's lakeside villa, where he discovers a collection of five enchanting Art Nouveau bowls, each one worth a small fortune. And each one encumbered with a secret. A challenge, which could give him the chance to grow as a person, or one that could cost him his life.

While private investigator Johann Friedrich von Allmen and his assistant Carlos are still celebrating the successful recovery of the valuable Dahlia picture, Carlos’ life partner Maria Moreno disappears. Not a lovers’ tiff, as Allmen’s factotum assumes at first, but the brutal revenge of those who feel they were robbed. Maria in exchange for the Dahlia picture – that is the kidnappers’ demand. But they did not reckon with old Dalia Gutbauer. For she is unwilling to hand over the picture, and has her own ideas about what she wants to do with it. This, of course, puts Allmen, Carlos and Maria in an extremely precarious situation. They need to act fast, and they all give their best in a dramatic race against time.

The bestselling crime novel series about the gentleman crook Allmen and his assistant Carlos sold more than 800.000 copies in German alone and was adapted for TV in 2017 by UFA fiction.

This fifth episode of the witty series revolves around lovers of art and the art of love.

Fine porcelain can be made into harmless figurines, or sexy artworks. Allmen and Carlos come across a secret hoard of valuable porcelain figures for lovers of explicit erotic depictions. A case that makes them work up quite a sweat because they are not investigating entirely of their own volition: A blackmailing accomplice has them in the palm of his hand.
