You are one of my purple case reviews for the "JULY CHALLENGE! Credited 7/30"  .

Death at every corner in this story! I was so glad when Luke had escaped the guillotine, but then, if him and Diane hadn't wandered off, they might be crushed by rocks.

Where is that castle? In California? The places in Europe that would have guillotines don't have earthquakes that strong. My grandmother, who lives about in the middle on the west side of France told me there was an earthquake once that kind of made the plates clink in the cabinets, but nothing worse.

In any case, that was a very dangerous field trip.
