Mr. Ernst here. This month the focus is on a surprise that turned up when researching a specific scene in this book, the fourth in Kathleen’s award-winning Chloe Ellefson Historic Sites mystery series.
Heritage Of Darkness (HOD) takes place within and around the wonderful, world-class Vesterheim Norwegian-American Museum in Decorah, Iowa. The story is set during December 1982, with historical flashbacks to the 1940s and 1960s.
This is the first Chloe mystery set at an historic site outside of Wisconsin. Other ‘out-of-state’ stories follow, but Kathleen intends to keep Chloe and Roelke firmly rooted at Old World Wisconsin and the Village of Eagle.

Chapter Thirty
As Kathleen crafted HOD, she decided to add an attempt on Roelke’s life.
An isolated location was required — somewhere between Vesterheim in downtown Decorah and a nearby farm that Roelke would be staying at. After consulting a local map and exploring the area by car, Kathleen picked a farm to the northeast, across the Upper Iowa River. (The farm’s exact location remains a secret to protect the resident’s privacy.)
Part of the farm’s appeal was its proximity to a bridge over the river. Roelke would have to cross it when making the one-mile walk between the farm and Vesterheim where he was taking a Norwegian chip carving class. The solitary red pin on the upper right side of the satellite image below shows where the bridge is located.

Above is a screen grab of a custom, interactive Google map of Decorah. It is one of many reader resources available on Kathleen’s HOD website page. (Map by Bonner Karger and Mr. Ernst.)
[NOTE: Each pin marks where a key scene in the book takes place. You can visit the HOD webpage to explore the map’s location photos and descriptions by clicking HERE.]
Kathleen and I initially scouted the book’s locations in warm weather, but given that HOD is set in December, we re-documented them in winter.

The modern bridge looked new enough that we decided to confirm it was there in December 1982. Local Archivist Midge Kjome directed me to bridge-related newspaper clippings and photos in the files of the Winneshiek County Historical Society . . . where I found the following.

Excerpts from “City, County Cut Ribbon to Open New Bridge” article, The Decorah Journal Newspaper, June 21, 1984. (Underlining added.)
Well, hunh. There was no bridge there when the ‘bridge’ scene was set!
Note from Kathleen: I hate it when that happens.
Making matters even worse, I discovered that the original “Twin Bridges” was an historic iron truss structure built circa 1880. It had just one-lane, no lighting, and lacked a sidewalk. It also had low, skimpy side-barriers, and offered a steep drop to the river.
In other words, it was perfect for the scene Kathleen envisioned.

As her readers know, Kathleen is a real stickler for historical accuracy. It’s the museum curator in her. In this case she made an exception, wielding her literary license to shift the tractor-bridge crash forward in time until after the book concludes. Problem solved.
Powerful things, literary licenses.
Below is an excerpt from the resulting scene, which starts on page 284.
Roelke walked north and east to the sounds of boots crunching snow and shovels scrapping sidewalks. The wind drove snowflakes almost sideways through the cones of light cast by street lamps. This may not have been my best-ever idea, Roelke thought as he approached the Upper Iowa River bridge. He was dressed well for wintry weather, but the snow was slowing him down. Best try to pick up the pace.
Good plan, but he’d no more than tromped onto the bridge when both feet flew out from under him. He landed, once again, on his ass. “Danger,” he muttered as he clambered to his feet. “Bridge surface may freeze before road.”
There were no lampposts on the bridge. He dug his flashlight from his pocket and scanned the single traffic lane, hoping to identify any additional icy spots. There was nothing to see but snow and the twin ruts of tire tracks. He set out again, this time keeping a hand on the railing.
He was half way across the narrow bridge when headlights appeared ahead. A car was approaching the bridge, too fast. “Slow down,” Roelke muttered. “Slow down. Slow down, Goddammit!”
The car didn’t slow down. As it hit the bridge the yellow beams went crazy, slicing the snow-hazy night. The vehicle was a dark blur, whirling, sliding, coming his way–Christ Almighty–coming his way and there was nowhere to go, nowhere to go. The bridge railing bore into Roelke’s hip until something had to give, bone or iron, and the car kept coming.
Roelke leaned out over the river, away from the speeding mass of steel. He heard the relentless shussh of skidding tires. The car was seconds away from crushing him.
Instinct pushed him over the railing in a wild twisting scramble. He managed to catch one vertical bar with his right arm. His other arm shot around too, and he clenched his right elbow with his left hand. The car hit the railing inches beyond the spot where he now dangled. The bridge shuddered. Roelke clenched every muscle. The car fish-tailed once or twice before the driver was able to straighten it out.
Then the car accelerated on toward town. Roelke watched the taillights disappear with stunned disbelief and rising fury.
We’d love to hear what you think, now that you’ve had the chance to compare the scene with some of the historical research used to write it. Please feel free to leave us a comment below.
HOD is available in trade paperback and multiple ebook formats from independent booksellers as well as Amazon and other online resellers. Both formats includes a map of Vesterheim, photos of the Norwegian folk art featured in the book, plus a cast of characters.
But Wait, There’s More!
Hopefully this article has piqued your interest in discovering more about the ‘people, places and the past’ that went into making HOD.
You can find a page full of details about it on Kathleen’s website, including a discussion guide, the Google map, the recipe for a dish served in the story, a slide show of objects featured in the book, public radio interviews with Kathleen, plus additional blog posts, links to booksellers that offer HOD — and more — using the link below.

Next month I’ll post an article on this blog about researching the next book in the Chloe Ellefson mystery series, Tradition of Deceit, which takes place in Milwaukee and Minneapolis.
