Sometimes, police and other sleuths need ‘inside information’ to solve a case. It’s not always easy to get that information, so there are times when a mole may be planted in a group. In fiction, we see plenty of moles in spy and espionage novels, but they find their way into lots of other novels, too.
Having a mole in a group – especially if other characters know there’s a mole – can add much to the tension in a story. And there are all sorts of possibilities for character development, too. We may not always like what moles do, but they certainly play a role in crime fiction.
In Agatha Christie’s After the Funeral, wealthy family patriarch Richard Abernethie dies, and his family gathers for his funeral. During that gathering, Abernethie’s younger sister, Cora Lansquenet, says that he was murdered. Everyone hushes her, and the matter is dropped. But privately, the family members begin to wonder. When Cora herself is murdered the next day, it seems clear that she was right. The family attorney, Mr. Entwhistle, visits Hercule Poirot, and asks him to investigate, and Poirot agrees. It’s not until later in the novel that the family members learn that Poirot is a detective, and that he’s been involved in the investigation. They also learn that Mr. Entwhistle has been asking his own questions and trying to find out the truth. And it’s interesting to see how they react when they find there’s been a mole in their midst.
In Walter Mosley’s A Red Death, Ezekiel ‘Easy’ Rawlins finds himself in a difficult bind. He’s gotten a threatening letter from Internal Revenue Service (IRA) agent Reginald Lawrence. It seems Rawlins owes thousands of dollars in taxes, and the letter indicates that if he doesn’t pay, he’ll go to prison. Rawlins can’t afford to pay the money, and is resigning himself to a prison term, when he gets a way out. FBI Agent Darryl Craxton contacts Rawlins and tells him that he can make Rawlins’ tax problems go away. In exchange, he wants Rawlins to get close to a man named Chaim Wenzler – a man the FBI wants to bring down as a communist (the novel takes place in the early 1950s, at the height of anti-communist paranoia in the US). Rawlins doesn’t see any alternative but to agree, and the plan is hatched. Wenzler is a frequent volunteer at the First African Baptist Church, and Rawlins becomes a mole there, finding out what he can about Wenzler. But he soon finds that he likes the man. The better he knows Wenzler, the less appetite he has for bringing him down, and that creates a serious dilemma.
In Jill Paterson’s Once Upon a Lie, Detective Chief Inspector (DCI) Alistair Fitzjohn is summoned back to Sydney from London, where he’s been taking some time off. The body of businessman Michael Rossi has been found on a marina at Rushcutter’s Bay, and an investigation needs to be launched. Ordinarily, the Kings Cross Police Station would handle this case, but they are shortstaffed, so Fitzjohn is seconded from the Day Street Station. He insists that his assistant, Detective Sergeant (DS) Martin Betts, come along, and that’s arranged. Fitzjohn and his team find that this is a complicated case, and several people involved aren’t telling everything they know. That’s hard enough, but Fitzjohn also learns that there is likely a mole at Kings Cross, whose job is to report to Superintendent Griegs about his activity. In the end, Fitzjohn finds he has to trust in his own instincts and in Betts…
Peter Lovesey’s Superintendent Peter Diamond also has to cope with a mole in The Last Detective: Introducing Detective Superintendent Peter Diamond. He and his team investigate when the body of famous TV actress Geraldine ‘Gerry’ Jackman is discovered in a lake. Diamond and his assistant, Detective Inspector (DI) John Wigfull, find that this case isn’t as obvious as it seems on the surface. The victim’s husband, Professor Gregory ‘Greg’ Jackson, is an obvious suspect, and he had motive. But there are several other people who might also have had a motive to kill the victim. In the meantime, Diamond has other problems. He’s still dealing with the fallout from an earlier case for which he got into trouble. Related to that, he’s learned that there is likely a mole among his team whose job is to keep tabs on him.
And then there’s Paul Thomas’ Death on Demand. In it, Sergeant Tito Ihaka is asked to return to Auckland from Wairarapa, where he was banished after an earlier case. He had accused Christopher Lilywhite of arranging for his wife’s murder. Lilywhite claimed innocence, and there was never quite enough evidence to pursue the case. What’s more, Lilywhite has money and ‘clout,’ and that was all it took to get Ihaka pushed aside. Now, Lilywhite wants to speak to Ihaka privately. Ihaka agrees, and Lilywhite confesses that he actually did pay to have his wife killed. He’s been diagnosed with terminal cancer, and wants Ihaka to know that there’s still a vicious multiple murderer out there, committing other crimes. Soon, Ihaka is on the trail of a very skilled, ruthless killer. At the same time, he learns that someone he works with is a mole. He finds out who that person is, but by that time, the mole has already caused all sorts of damage.
And that’s the thing about moles. They can wreak all sorts of havoc and trouble. But they certainly can add tension to a crime novel.
