Marie Benedict is a former lawyer who’s written ten novels. Her latest book, “The Only Woman in the Room,” is a work of historical fiction about the actress from the golden age of Hollywood, Hedy Lamarr. In addition to her acting career, Hedy was also an inventor. In the 1940s, she created a radio guidance system that eventually led to the development of Bluetooth and Wi-Fi technology. Marie Benedict talks this hour with journalist and director of arts and culture for the city of Detroit, Rochelle Riley.

Lynne Olson, Elizabeth Berg, and Elizabeth Letts all join Writers Series co-founder Doug Stanton on the stage of the City Opera House to talk about their work. Author and journalist Lynne Olson is known for her books about history, especially World War II. Her latest is “Madame Fourcade’s Secret War.” Elizabeth Berg writes novels, such as “Open House” and “The Story of Arthur Truluv.” And Elizabeth Letts writes books of non-fiction and historical fiction. Her latest is about “Wizard of Oz” author Frank L. Baum’s wife, Maud Baum. Doug asked each author to describe their latest book.

Half a century ago, hundreds of pairs of piping plovers lived in the Great Lakes. But by the 1980s, they were on the verge of extinction and only a dozen pairs remained.

Over time, wildlife biologists have helped increase the population. But it’s still well below a stable number and each year there’s a new threat.

Piping plovers are small, stout white-gray birds. In the spring, they can be found nesting on the shores of the Great Lakes. Once a fixture on the lakes, the birds are now on the federal Endangered Species List.

Frogs and toads are highly sensitive to habitat degradation, and that makes them a good barometer for environmental health.

Every year volunteers from the Michigan Department of Natural Resources do a listening survey to determine which species of frogs and toads are present and how abundant they are.

Volunteer Kathy Gray's survey route is on Old Mission Peninsula.

“Well, I do love the toads. I love the trilling toads," Gray says.

This week on the Interlochen Collection, it’s a “titan” of an episode. We devote the entire hour to a performance of Gustav Mahler’s Symphony no. 1, the Titan, from 1987.
