Tom doesn't look like a member of the secret service; however he proves to be very observent. Give evidence of this from this chapter.

Sorry, this is a short answer forum. Students need to write their own paragraphs and essays. As for Tom's skills of observation, he finds various pieces of evidence in Chapter 15. While examining the site, he noticed fresh oil in the lock, found mud on the stairs, hoof prints, rust worn off of the ring that held the horse's tethers, and food the horses hadn't eaten.
