The murder of an expensive “call girl” by a rich client looked perfectly ordinary. But… the killing was filmed by a hidden camera onto tape. Under mysterious circumstances, the only eyewitness who could shed light on what happened died. And finally, the person recorded on the tape—accused of the murder—swears that at the moment of the crime he was elsewhere… That’s how a new case for special agent Dorngo begins. At first glance it seems simple enough to be funny, but it turns out to be one of the most mysterious and unusual in Dorngo’s entire career.
