In this madcap journey, a bestselling journalist investigates psychopaths and the industry of doctors, scientists, and everyone else who studies them. The Psychopath Test is a fascinating journey through the minds of madness. Jon Ronson's exploration of a potential hoax being played on the world's top neurologists takes him, unexpectedly, into the heart of the madness industry.

An influential psychologist, who is convinced that many important CEOs and politicians are, in fact, psychopaths, teaches Ronson how to spot these high-flying individuals by looking out for little telltale verbal and nonverbal clues. And so, Ronson, armed with his new psychopath-spotting abilities, enters the corridors of power.

He spends time with a death-squad leader institutionalized for mortgage fraud in Coxsackie, New York; a legendary CEO whose psychopathy has been speculated about in the press; and a patient in an asylum for the criminally insane who insists he's sane and certainly not a psychopath.

Ronson not only solves the mystery of the hoax but also discovers, disturbingly, that sometimes the personalities at the helm of the madness industry are, with their drives and obsessions, as mad in their own way as those they study. And that relatively ordinary people are, more and more, defined by their maddest edges.

Beka Cooper is no longer a Puppy. She's a Dog now - a full-fledged member of the Provost's Guard, which keeps the peace in Corus's streets. Beka's natural skills of observation and tenacity are augmented by her unusual magical talents, which allow her to gather information both from pigeons and from the eddies of dirt and dust that swirl on street corners.

But even her magic isn't very useful when unrest comes to Tortall's capital in the form of counterfeit coins, which turn up in shops all over the city. Merchants raise prices to cover their losses, and with winter coming on, hikes in food and fuel costs could spell disaster - most of all for the city's poor.

The Dogs discover that gamblers are bringing the counterfeits from Port Caynn - and that the Port Caynn Dogs don't seem to be doing anything about it. Beka and her mentor, Clary Goodwin, are chosen to go undercover in Port Caynn and find out what they can. And wherever Beka goes, so do some of her animals. Departing from Corus with her are the scent hound Achoo, newly assigned to Beka, and the pigeon Slapper, who carries the voices of the dead.

In Port Caynn, Beka and Goodwin delve deep into the gambling world. There Beka meets a charming bank courier, who may be involved in the counterfeiting ring. Things come to a head just as Goodwin returns home to report in Corus. It won't be enough for Beka to be her usual "terrier" self. She'll have to learn from Achoo to sniff out the criminals - to be a bloodhound.
