This is an action packed story from beginning to end. It has all the makings of a thriller. One thing I do find a bit distracting is the change between past tense and present tense. For example,
Maria stayed in the bathtub longer than usual. As she pats her hair dry and puts on comfortable clothes, you kinda know that she's not going to bed.
You begin with the past tense but then switch to the present tense. I think the story works well in the past tense and it should be kept throughout the story. So, the above sentence should read:
Maria stayed in the bathtub longer than usual. As she patted her hair dry and put on comfortable clothes, you kinda knew that she was not going to bed.
I hope this helps. It was an entertaining read.
