BTS: Mr. Rose and the Hound

Following on last week’s theme, here’s another quick crime mystery:

Poor Mr. Rose was found dead in his study by Mr. Hound.

Mr. Hound recounted his dismal discovery to the police:

“I was walking by Mr. Rose’s house when I thought I would just pop in for a visit. I noticed his study light was on and I decided to peek in from the outside to see if he was in there. I walked through the snow towards the window, and I had to wipe the condensation off the window to see inside. That is when I saw his body. I kicked in the front door to confirm my suspicions of foul play. I called the police immediately afterward.”

The officer immediately arrested Mr. Hound for the murder of Mr. Rose.

How did he know Mr. Hound was lying?

As for the solution to last week’s mystery, Mr. Jones was certainly lying about the details of the matter, as the dead man was shot in the stomach, not the back.
