The Disappearance of Natalie Firth

Harry the eight year old son of Malcolm and Natalie Firth, engages Larry Dexxman to find his mother, but he has no idea of the can of worms that Larry is about to open.

Larry's wife Penny, Neil and Denise his two new assistants, and Sally his tiny Shih-Tzu/Yorkshire terrier cross, embark on a mission to find her
.
With the help of MI6, they delve into the murky depths of Malcolm's life and are astounded and horrified to find that he has links with Vincente Vasquez, a known villain, suspected of drug smuggling and murder.

When Special Branch shows an interest in his case, Larry finds that he has unwittingly become embroiled in an ongoing espionage investigation, which seems to be inexorably linked to Natalie's disappearance.

Whether Natalie is alive or dead is a moot point, when keeping himself, his friends, and Harry alive, becomes the order of the day.
