Mr. Whitmore: A Short Story

Yesterday I opened my laptop and noticed a strange email. There was no subject line and it said it was from someone named Mr. Whitmore. Odd. I didn't know a Mr. Whitmore and I thought nothing of it when I decided to open the email. But I froze when I saw what was written. 

Open the closet door.

I froze and held my breath when I read those words. What the hell? I turned from my desk and looked behind me at my closet. It was quiet in the room and I could hear the slight bustling from the street outside my apartment building. I shook away my nerves and sent the weird email straight to the trash folder. I spent the next few hours working on music arrangements when a notification popped up on my screen. A new email. I clicked on the notification to check and was taken aback. Another email from Mr. Whitmore. I hesitated before I anxiously clicked the email open.

Please let me out.

I quickly turned to look at my closet. There didn't seem to be anything out of place. I got up from my desk and decided to take a walk down to the building lobby to check my mailbox. I was expecting a package that day after all. I made my way down and was greeted by Janice, the nice elderly lady that lived on the ground floor. I turned my key to open the mailbox and unfortunately was not greeted by the package I was expecting but there was one thing in there. An envelope with Mr. Whitmore's name written on it and nothing else. I held the unopened letter in my hands and Janice must have noticed the expression on my face.

"Is there something the matter, dear?"
I turned the letter to her. "Is there a Mr. Whitmore in this building?"
"Oh... Oh yes, dear. There was."
"Was?" I asked. "Did he move? I think this letter is for him."
Janice looked saddened. "Poor dear... He had passed away. They found him hanging in his closet."
All I could do was stare at her while clenching the letter. 
"By any chance, do you remember which unit he was in?"
She thought for a moment. "Oh... I do believe he was in B5."
Janice waved to me and retreated down the hall. B5 was my apartment. I glared at the envelope in my hands and quickly opened it to see what it said.

I'm so tired.
