Mr. Hitchcock, in his own words offers his views of the ideal setting and time for reading: "I feel that evening is the best time to approach the stories I have gathered together. An easy chair, a darkened room and a pool of light to read by offer the ideal setting in which to enjoy the varied attractions of these tales. If at all possible, avoid sharing the room with a teen-ager playing records that thump, shriek and wail at you. This is bound to be distracting. Unless of course, you are a teen-ager yourself. But if you are a teen-ager, what are you doing reading this book? Shouldn't you be out organizing a protest against something?"

"So much for that. This time, as you will see, I have assembled a sample of stories embracing many aspects of the mystery tale. There are thirty-one of them. If you ration yourself and read one each night, they will last you exactly a month. Of course, you will have to pick a month with thirty-one days and start on the first. But this is for perfectionists only. I don't insist. I am an advocate of the permissive school of reading."

"Start anywhere and read as fast as you please. Now I must get back to the laboratory. There's work to be done."
