For not even a 100 pages this book felt a lot longer than it was. 
most of that had to do with the pretty slow pacing and the tone it was written in that felt a bit like it was just trickling along. 

that’s not bad and if you enjoy a quicker read in sense of page count but like the pacing of a longer book? this will be a perfect read. 

i prefer a short story to be quick paced and fast acting especially if it’s a mystery or a thriller type of book. if i want slower pacing in that genre i read a full length one! but those short stories? those i read if i want quick action and not a lot of pattering around. 

it’s apersinal preference but since i didn’t get what u wanted from this i was a i it disappointed by this especially since the summary sounded a lot more action packed than this needed up being. 

overall it’s a good story and as i said if you want something that reads slower paced but is still under a 100 pages and it’s a crime story? go for it!
