Richard Coles and Michelle Ackerley are joined by writer Joanne Harris; broadcaster Peter Snow; wildlife journalist and wasp expert Ben Aldiss and chef Joshna Maharaj.

Born in Barnsley, writer Joanne Harris MBE was a teacher for 15 years during which time three of her novels were published including Chocolat in 1999 which was made into an Oscar-nominated film starring Juliet Binoche. Since then, she has written 15 more novels, two novellas, two collections of short stories, a Dr Who novella, guest episodes for the game Zombies Run, the libretti for two short operas, several screenplays, a musical and three cookbooks. She is guest director of this year's Yorkshire Festival of Story and her new book Orfeia is out in September. You can find more information about the festival via yorkshirefestivalofstory.com

Most of us get as far away as possible when we spot a wasp, but Ben Aldiss does just the opposite. A wildlife journalist and teacher who was known as Dr Wasp by his students, Ben studied wasps for his doctorate and is an expert in their behaviour and what provokes them to sting. He joins us to discuss some of the myths people believe about the insects, how to avoid getting stung, and some of his own experiences working closely with them.

Joshna Maharaj is a chef who lost her sense of smell about six years ago. She talks about the devastating effect of anosmia, how she coped with her loss in the kitchen environment and why she kept it a secret for many years. She is now undergoing smell training to help her regain her lost sense and talks about her olfactory experiments and how smell is directly connected to memory and emotion. Take Back the Tray by Joshna Maharaj is out now.

There isn’t much ground that broadcaster, journalist and historian Peter Snow hasn’t covered in his career: the first presenter of Newsnight when it launched in 1980, and the face of the election swingometer - he’s since moved on to making documentaries with his son, Dan, and now, writing books with his wife, Canadian journalist Ann MacMillan. He joins us to chat about their new book which uses 50 documents to illustrate global history. He also reminisces about his career as a journalist, surviving a plane crash and the story of his unwitting audition for the role of James Bond. Treasures of World History: The Story of Civilisation Told Through the 50 Most Important Documents by Peter Snow and Ann MacMillan is out now.

Writer Matt Haig chooses his Inheritance Tracks: Don't You Want Me by the Human League and It's Quiet Uptown from the Hamilton soundtrack. And there's a thank you to a stranger who saved a dog's life.
