|I love the feel of a Hitchcock hand in this, but think the drama could be built more effectively. Because the title indicates that this is part one of a continuation, the following remarks may not truly apply, but I think, with a little tweaking ,it could stand on its own as a piece of flash fiction.
Going under that assumption, I would suggest the following:
(1) Don’t give it away in the title
(2) Make mention of a sharp chef’s knife that he uses in his cooking.
(3) Don’t mention giving up the meds until immediately before “I think next Wednesday…….go to the supermarket to get some groceries and the beautiful blond lady.” That would be a chilling last line!
A few minor structuring suggestions:
“My hobbies include reading (I love the horrors from the masters like James Herbert and Shaun Hut son), walking & like to take some …….would change to “and taking …..”
“This is why I shop through…..would change to “during”
“Her shoulder length blond hair looks like silk and when she leaned over I could tell that it smelled like strawberries. “ Would change this to make the verbs agree and delete “I could tell” as it isn’t necessary. In other words, “Her shoulder length blond hair looked like silk and, when she leaned over, it smelled like strawberries.”
I hope this is helpful. Again, I think this could be a tasty little tidbit of flash fiction with some tightening. I’ll look for part 2 to see where you’ve gone with it.
