|Hey John,

|Congratulations on your becoming a firefighter. Let me welcome you with a special present.

|I feel like you need a memorable event to mark the start of your career. Make no mistake, the event I have planned for you will not easily be forgotten. So, here is the deal. There's going to be a fire, but not just one fire! There will be a fire every day for six days!

|You could say that, you're going to have a lot of extra work to do. Hahaha!!

|Now I'm a fair person, so In return, I'll tell you who set fire to your home three years ago. Consider it an incentive to do the best possible job.

|But this isn't going to be easy! 

|I'll leave one clue at each fire, so keep a sharp eye out for it, my friend.

|Oh, one more thing before I go. The arsonist is one of your colleagues at the fire department.
