"For many centuries," he began at last, "there has been a curious belief among you Christians that the Jewish rabbinate possesses mystic knowledge of the occult. No doubt that belief derives from the early Middle Ages when the Jews became in part the means by which the science and culture of the Saracen East was brought to the ignorant barbarous West. That service was turned against us by the superstitions and prejudices of Christendom and we were regarded as akin to sorcerers and witch-masters. Even today in Germany, we are paying for our crime of having brought enlightenment to Europe in the Dark Ages." "Then you can't help me?" I asked. "I did not say so, Mr. Tompkins," the Rabbi replied. "Certainly I cannot help you in any occult manner. I cannot pick a book from the shelves, mutter a few words in Hebrew and resolve your spiritual problems with a whiff of brimstone. The casting out of devils is not included in Judaism. Indeed, it has gone out of fashion in Christendom." "What can you suggest?" I inquired. "Many important events, including the possible capture of a dangerous Nazi spy, depend on my recovering my memory." "Even with that inducement," the Rabbi remarked with an ironic smile, "I am not in a position to urge any particular course on you. Assume, for the sake of argument, that you are the victim of what is called a demoniac possession, Mr. Tompkins. Are you sure that you would be benefited by casting out the soul of Frank Jacklin and resuming command of your own personality? Is not Winfred Tompkins a better and happier man under the influence of Jacklin than he was as himself? In other words, Mr. Tompkins, you may not be seeking to cast out a devil at all, but an angel of the Lord. Of course, I am speaking in moral metaphor and not as a scientist or a theologian. My advice to you would be to ignore your loss of memory and live out your life as best you can and be thankful that whatever it is that caused this change has been for your betterment and has brought happiness to others." I shook my head. "I know that I am foolish to insist, Rabbi Da Silva," I said. "What you say is just about what the psychiatrists advised. Yet I must open that locked door and see what is hidden in the secret room." Da Silva smiled gently. "Yes," he agreed, "I see that you must. Bluebeard's wife felt much the same and the charm and universal meaning of that great fable is that humanity must always open the closed doors, even at the risk of destruction. All wisdom urges us to leave well enough alone, yet our instinct is wiser than wisdom itself. God bless you, Mr. Tompkins, and may you come to no harm if you find the key to this locked room." "Thank you, sir," I said. "Now there remain only the Catholics. Perhaps a parish priest--" "I shall be very much surprised if a priest advises you differently, Mr. Tompkins," the Rabbi observed. "Drop in again some time and tell me, will you?"
