From The Grey House:
Carlos took the glass willingly, swirling the dark liquid, warming it. He looked up at the vampire who loomed above him and raised the glass in a toast. They clinked glasses and Carlos downed his drink, while Vincent sipped at his.
A shudder passed through Carlos as liquid fire rushed down to his stomach. The shudder stopped and he placed the glass on the desk. “You shouldn’t have wasted your good brandy on me tonight.”
Vincent swirled the liquid and took a sip. “Did you enjoy it?”
“Yes.” “Then it wasn’t wasted.”
