Inspector Chelmey and a handful of crime scene specialists arrived on the scene just as the sun disappeared over the west hill. Professor Layton stepped into the corridor outside to confer with the inspector, so as to let forensic team do its work.
"My team says you found the body in the salon, Layton. Good work!" Chelmey slapped Layton on the back — perhaps a little too hard — then quickly resumed his gruff demeanor. "But I still need answers, dammit! Who did this? And how did the killer even get into the house?"
"Hmm," Layton intoned. "Two very interesting questions."
Layton ripped a sheet of paper from his notebook and handed it to the inspector. "Take a look at this map I've drawn of the first floor. I've marked several spots on the map where I found bloody handprints, no doubt left by Dame Mortum."
Chelmey grasped the paper with both hands and turned it back and forth like a steering wheel, trying to make sense of it. "My word!"
"Indeed, inspector. It appears that Dame Mortum was attacked by our mystery assailant, yet managed to drag herself around the house to leave behind a message for us."
"A message? What're you goin' on about now? Do you know who killed her?"
"Hmm," Layton repeated. "Not quite yet. But I think her bloody trail will reveal a particularly bad habit of hers that, coincidentally, explains how the killer was able to enter the mansion. From there, we should be able to deduce the identity of the killer."
"Hmph! I don't have half the brain you've got, Professor. Just let me know the answer once you've solved it, eh?"
