First of all, cool idea! I loved the synopsis you provided (above), it caught my imagination, and make me curious to see how you proceeded...
I quite enjoyed the chapter - it needs editing of course, some tense issues, and minor spelling oops... but the story line felt solid to me, and I wanted to know who phoned!
I too work at home, though I have for years, so I can't blame Covid 😬 ... but finding TIME to write is always one of the hardest things - I can get lost in the story, and then nothing that makes money gets done.... or I can work, and the stories nag at the back of my mind.
Like you, I joined here for feedback on my work - not necessarily planning/hoping to publish, but wanting to improve. What I learned was how much I had to learn (!), which has led to a LOT of workshops - many of them great lectures available free here.
If you can make the time, I think you should continue... I for one would love to read more. Good luck!
