“Wait.” Marcus’s face was still as he concentrated. “When exactly was Benjamin made?”
“In the early twelfth century,” Matthew replied, frowning. “After the First Crusade.”
“And when did the witch in Jerusalem give birth to a vampire baby?”
“What vampire baby?” Matthew’s voice echoed through the room like a gunshot.
“The one that Ysabeau told us about in January,” Sarah said. “It turns out you and Diana aren’t the only special creatures in the world. This has all happened before.”
“I’ve always thought it was nothing more than a rumor spread to turn creatures against one another,” Ysabeau said, her voice shaking. “But Philippe believed the tale. And now Diana has come home pregnant. . . .”
“Tell me, Maman,” Matthew said. “Everything.”
“A vampire raped a witch in Jerusalem. She conceived his child,” Ysabeau said, the words coming out in a rush. “We never knew who the vampire was. The witch refused to identify him.”
Only weavers could carry a vampire’s child—not ordinary witches. Goody Alsop had told me as much in London.
“When?” Matthew’s tone was hushed.
“After the First Crusade.” Ysabeau looked thoughtful. “Just before the Congregation was formed and the covenant was signed.”
“Just after I made Benjamin,” Matthew said.
“Perhaps Benjamin inherited more than blood rage from you,” Hamish said.
“And the child?” Matthew asked.
“Died of starvation,” Ysabeau whispered. “The babe refused his mother’s breast.”
Matthew shot to his feet.
“Many newborns will not take their mother’s milk,” Ysabeau protested.
“Did the baby drink blood?” Matthew demanded. “The mother claimed she did.” Ysabeau winced when Matthew’s fist struck the table. “But Philippe was not sure. By the time he held the child, she was on the brink of death and would not take any nourishment at all.”
“Philippe should have told me about this when he met Diana.” Matthew pointed an accusatory finger at Ysabeau. “Failing that, you should have told me when I first brought her home.”
“And if we all did what we should, we would wake to find ourselves in paradise,” Ysabeau said, her temper rising.
“Stop it. Both of you. You can’t hate your father or Ysabeau for something you’ve done yourself, Matthew,” Sarah observed quietly. “Besides, we have enough problems in the present without worrying about what happened in the past.”
Sarah’s words immediately lowered the tension in the room.
“What are we going to do?” Marcus asked his father.
Matthew seemed surprised by the question.
“We’re a family,” Marcus said, “whether the Congregation recognizes us or not, just as you and Diana are husband and wife no matter what those idiots in Venice think.”
“We’ll let Baldwin have his way—for now,” Matthew replied after thinking for a moment. “I’ll take Sarah and Diana to Oxford. If what you say is true, and another vampire—possibly Benjamin— fathered a child on a witch, we need to know how and why some witches and some vampires can reproduce.”
“I’ll let Miriam know,” Marcus said. “She’ll be glad to have you back in the lab again. While you’re there, you can try to figure out how blood rage works.”
“What do you think I’ve been doing all these years?” Matthew asked softly.
