She turned back toward her camera, which had been automatically snapping pictures of the mural at various focus points until she’d felt the train move. She suddenly froze. Something was different from when she’d been crouching on the floor as the train had started barreling down the track. The first several dozen photos had revealed nothing, but the electronic viewfinder screen now showed something else entirely.

It showed the painting beneath the painting.

Jane felt her breath leave her as she watched. With each focus point, the image grew richer and more detailed. Finally, when it started to fade, Jane grabbed the camera and stepped back through the photos until she found the clearest one.

The hidden image was similar to the one she was accustomed to seeing with the shepherd boy with the brown dog, playing children, and the lady with the blue parasol. But there was one major difference: This mural included a train and a station with a sign reading BENTLEY IND. Only details relating to the train and station had been erased in the final mural.

BENTLEY IND? Jane pulled out her phone for a quick search.

She found what she was looking for in seconds.

She gasped.

The phone rang in her hands. It was Caleb. She punched the TALK button.

“Are you okay?” He was worried. “We took some gunfire back there.”

“Tell me about it. But I’m fine. Are you both all right?”

“For the time being. But we threw Bohdan’s men back at the railway station into an uproar. Lots of activity going on. They’re bound to be after us any minute. We’re trying to figure out the next move. There might be more bullets flying so don’t be moving around the car. Keep down!”

“I will. Because there’s no reason for me not to any longer.” She drew a deep breath. Then her words came as fast as she could get them out. “Listen, Caleb. This has to be quick. I found what I was looking for in the mural. I know why no one could ever find the treasure.”

“What?”

“You heard me. MacClaren decided to hide it. It’s because the instructions’ starting point was the end of the first branch line past the McNaughton Branch. Anyone who would go looking for the treasure wouldn’t find the landmarks referenced in the instructions. No big rock, no forked stream. No waterfall or ancient cemetery.”

“That’s right. It’s why the treasure map was bogus.”
