Johnny took a little time to actually grind three sleeping pills into powder, as quietly as possible, and hide the powder in a small plastic pouch. He hid it beside the bottle in a drawer, under his underwear. He then went to the living room, book in hand. He made himself comfortable in a chair, and started reading.
It was captivating indeed, a great novel from one of the masters of science fiction. Too bad he had to use such a masterpiece of sci-fi literature for coverage! He had to have his parents think he is absorbed in the reading of the book. Well, that surely was the impression he gave them, because they tried to talk to him a few times but he seemed reluctant to answer, literally lost in space.
Actually, it was not THAT hard to give them this impression. The book was indeed great, and the whole matter was really very important for him to just let things go on their own; he had conceived a good plan, and now it was the final stage. He HAD not to mess anything up now.
After reading about 130 pages straight, he couldn't read any more; at the very least he deserved a small break. He left the book on the chair, and stretched his body a bit. Angela saw him.
-Tired, honey?
-Yeah, mom. I need to get my eyes of the book for a while. Man, it is a damn good book!
-It sure is beautiful, honey. Would you like to help me a bit, to rest your eyes? You mustn't get blind on me, sweetie pie!
-O.K. mom, but just for a while, O.K.? And don't expect me to be fast, O.K.?
-Sure, baby.
So he helped his mom around the house, as lazily as possible and just a bit, as he said. At one particular instant, his mom sent him to get a few things from the master bedroom. On the way back, Johnny quietly passed by his own room, took the small bottle and the pouch, put them in a pocket, and went back. As his pants were baggy, nobody would see the small bulge in the pocket, or at least so he thought. His heart was beating rather fast for the first few minutes back with his mother, but soon he realized she hadn't noticed a thing.
After some time, Angela told him there were no more chores to be done around the house, and they could rest now. Johnny volunteered to prepare dinner - just a glass of milk, to be consumed slowly in front of the TV. She happily agreed. Soon, Ralph and Angela were in the living room, and Johnny was in the kitchen, heating the milk. His mom wore a nightgown, which was perfect for his purposes; he wouldn't have to undress her. He took three cups from the cupboard. He chose them so that there was a tiny detail visible in each one, so that he wouldn't confuse the cups -- that would surely mean disaster for his plans!
After a while, he turned the stove off and poured milk in the cups. He took the jar that contained sugar, and a spoon. He put sugar in all three cups. He took the pouch with the powder and emptied its contents in the two jars of his parents, taking care to over-drug Ralph and to slightly under-drug Angela. He took the bottle out of his pocket, and dropped 5-6 droplets in his mom's milk. That should do it, he thought.
He took a tray, put the cups on it, and carefully led himself to the living room. He gave each one his own cup, making sure that the cups were right. Then he sat down under the small lamp, sipped a small gulp of his milk, and resumed reading the book, in the same totally absorbed fashion as before. However, what he really did was to wait for his parents to start drinking, hoping they wouldn't detect anything. His heart was beating like a drum.
