Wolfe had a fair deal of experience with explosions, and it only took a few minutes of examination to realize that this one had started somewhere near shoulder height.
That was why it had so effectively blown out the front windows and door of the building, there was no furniture to stop it.
The nearby display counters were collapsed, not pushed out and up, as they would have been if the explosion had been at floor level, and the damage to the back of the building was much worse than the front.
The only part he couldn't determine is what had created the explosion. There was nothing in the house or shop originally that could have done it, and whatever it was had created a blast that could take out the standard Rank Two protective barriers on the building.
With a lack of evidence surviving the explosion, Wolfe headed back out into the street to help with the cleanup.
