Saving a Life or Extinguishing the Fire?

Just as Francis Larson and Yvette Larson were about to arrive at the Larson family's old residence, they each received a text message: "Do you want to save a life or extinguish the fire?"

The pair was still trying to figure the message out when Francis Larson's phone rang. He glanced at the number. 'It looks familiar. I didn't save it, but I'm sure I've seen it before. I can't put my finger on it though.'

'However, it isn't the time to think about it.' Francis Larson picked up the call. 'Who could be calling me at this time? They probably have something to do with the message.'

He was greeted by a familiar voice. "Francis, do you know who I am?"

"Hilary Stone, it's you!"
