“Dr. Maxwell stopped by earlier. He promised to buy me a new lab.” She smiled. “Though he was a little disappointed that I didn’t know what happened.”

“You don’t know what caused the explosion?” Loren asked.

“No. I thought it came from a neighboring lab.”

“From what I saw of the damage, it appeared that the blast was centered in the room where I found you,” Pitt said.

“Yes, that’s what Dr. Maxwell told me. I’m not sure he believed me when I told him that there was nothing in my lab that could have caused that large of an explosion.”

“It was a pretty powerful bang,” Pitt agreed.

Lisa nodded. “I’ve sat here and pictured every element and piece of equipment in that lab. All of the materials we have been working with are inert. We have a number of gas tanks for the experiments, but Dr. Maxwell indicated that they were all found intact. The equipment is basically benevolent. There was simply nothing volatile I can think of that would have caused such a thing.”

“Don’t blame yourself,” Loren said. “Maybe it was something with the building, an old gas line or something.”

They were interrupted by a stern-faced nurse who came in and propped up Lisa’s bed, then slid a tray of dinner in front of her.

“Guess we better be on our way so that you can enjoy the hospital’s epicurean delights,” Pitt said.

“I’m sure it won’t compare to last night’s crabs,” Lisa said, struggling to laugh. Then her face turned to a frown. “By the way, Dr. Maxwell mentioned that an old car parked in front of the building was severely damaged by the explosion. The Auburn?”

Pitt nodded with a hurt look. “Afraid so,” he said. “But don’t worry. Like you, she can be rebuilt to as good as new.”

There was a knock on the door behind them, then a lean man with a ragged beard entered the room.

“Bob,” Lisa greeted. “I’m glad you’re here. Come meet my friends,” she said, introducing Loren and Pitt to her lab assistant Bob Hamilton.

“I still can’t believe you made it out without a scratch,” Lisa kidded him.

“Lucky for me I was in the cafeteria having lunch when the lab went boom,” he said, eyeing Loren and Pitt with uncertainty.

“A fortunate thing,” Loren agreed. “Are you as stumped as Lisa by what happened?”

“Completely. There could have been a leak in one of our pressure canisters that somehow ignited, but I think it was something in the building. A freak accident, whatever the source, and now all of Lisa’s research is destroyed.”

“Is that true?” Pitt asked.

“All the computers were destroyed, which contained the research databases,” Bob replied.

“We should be able to piece it together once I get back to the lab . . . if I still have a lab,” Lisa said.
