“It’s been five days since his murder,” she said, “and not a single Muslim leader has bothered to condemn it. In fact, given a chance to do so by the Dutch media, they have chosen to blame it on him. Where are these so-called moderate Muslims one always hears about in the press? Do they exist or are they merely figments of our imagination? If one insults the Prophet Muhammad, our Muslim countrymen pour into the streets in a sacred rage and threaten us with beheading. But when one of them commits murder in the Prophet’s name…”

Her voice trailed off. Gabriel completed the thought for her.

“The silence is deafening.”

“Well put,” she said. “But you didn’t come to Amsterdam to listen to a lecture by me. You have a job to do.” She scrutinized him carefully for a moment while they walked side by side in the narrow street. “Do you know, Herr Kiever, it was exactly a year ago that Professor Rosner first told me about his relationship with a man named Rudolf Heller and what I was to do in the event anything ever happened to him. Needless to say, I hoped this day would never come.”

“I understand you and Professor Rosner were very close.”

“He was like a father to me. I had a dozen other job offers when I completed my degree—jobs that paid much more than the Center for European Security Studies—but I chose to work for Professor Rosner for a pittance instead.”

“You’re a historian?”

She nodded. “While I was researching my thesis, I learned that we Dutch have a habit of trying to reach accommodation with murderous ideologies, be it National Socialism or Islamic fascism. I wanted to help break that cycle. Working for Professor Rosner gave me that chance.” She pushed a stray lock of hair from her forehead and looked at Gabriel. “I was at Professor Rosner’s side for five years, Herr Kiever. I had to endure the taunts and threats as well. And I believe that entitles me to ask a few questions before we start.”

“I’m afraid asking too many questions about who I am and why I’m here will make your life more complicated and dangerous than it already is.”

“Will you permit me to posit a hypothesis?”

“If you insist.”

“I don’t believe Herr Rudolf Heller is Swiss. And I certainly don’t believe he’s a venture capitalist who had an interest in supporting the work of a terrorism analyst in Amsterdam.”

“Really?”
