From The Grey House:
His friend called an hour later with the news. Markus was still human, but Edwin had been trying to seduce him to his side. Markus, happy with his current boss, kept denying the vampire. Joseph, wanting to keep the human safe, had placed him on Vincent’s private jet. Markus was being sent to New York. It was safer for him there. Vincent’s sire, Lorraine, ran the city and was always happy to shelter Vincent’s friends, especially of the male variety. Although Vincent was glad Markus was safe, he was rather perturbed. He was losing two of his most loyal humans on the same night. It left him with a bad taste in his mouth.
