How does Charlaine Harris use imagery in Shakespeare's Landlord?

Imagery:

"I worked the bag up a little at the side and found a hand; I put my fingers on the wrist, where a pulse should be. In the chilling Shakespeare night, I squatted in the middle of the trees, holding hands with a dead man. And now I'd left my fingerprints all over the plastic bags."

"The blow that had killed Pardon had been delivered by someone strong and someone furious. This murder, I thought, pausing to stretch my back muscles, had been a murder of impulse, though whose impulse, I hadn't the foggiest notion."
