Hello, I'm Harriet Gilbert.

Thank you for downloading a good read, the podcasts,

where two guests and I recommend books we love and describe why we love them.

We don't always see eye to eye, but I hope you'll find some great reading suggestions here.

Hello, today are tigers coming to tea with us, a slightly alarming

experience. With me to introduce their good read are first the actor Tobias Menzies,

aka Prince Philip for fans of the Crown, equally known for his double role in the hit TV series

Outlander. Currently, Tobias is filming a second series of This Way Up for Channel 4.

Here with him is the playwright, video games writer and novelist,

Githa Lodge, author of the best-selling Jonah Sheen's Mysteries.

The third book in that series, Lie Beside Me, is published this very week.

Tobias, Tobias, would you start us off with your choice of a good read?

What is it?
