Crime across time

"A puzzling mystery is afoot! Thankfully, Caper Cove's finest are on the case, but the investigation takes a turn for the strange when the town's resident evil genius, Brain Sturgeon, dives into a portal to the past. Fighting crime, dodging dinosaurs, and wrangling old West outlaws, these two best friends have gotten tangled up in a mystery fit for the ages. Will this dynamic duo be able to restore the past, present, and future--or will time as we know it be lost forever?"--Provided by publisher.
