Le Bureau

It's been ten years – an eternity – since Edwige, my dear sister, mysteriously vanished without leaving a farewell letter or even taking a suitcase. We were very close, and I can't see what could have driven her to disappear voluntarily. I know she didn't commit suicide. Unlike my parents, I haven't lost hope of finding her alive. But this hope is accompanied by a terrible fear that my sister is being held captive by a sadist who has been torturing her for a decade. This possibility haunted my nightmares for a long time until I learned that Edwige's husband, Professor Christianus, had received a small fortune from the life insurance for the presumed death of his wife. Now, I am convinced that this sinister and cold man is involved in this tragedy, as Edwige had confided in me a few weeks before she disappeared that her husband was desperately short of funds to continue his obscure experiments. It's possible that the evidence of his guilt is in his office. I rely on your detective skills to gather them. You are my last chance!
