The House Across the Lake

I've been taking on a challenge to see if I can guess the ending to a riley sager book. I've read his home before dark, middle of the night, lock every door, and the only one left and so far i am 0/5 now on this challenge. I have to say each riley sager book I consume I am just more and more obsessed with his writing style, the character sets, and the overall stories he builds. definitely 10/10 recommend this one.
