A cold, sweet treat well suited for a hot summer day. Start with the person we are celebrating today, followed by an erudite way to point out the original author made a mistake. Finish with a French article.

I reflect what stands before me, yet hold no memory. I double the world, yet make no sound. A silent mimic of your every move, I stand.

Usually full of cobwebs and dust, the afternoon sun piercing the darkness like a needle, sharp and crisp. Boxes on boxes, I'm full of forgotten treasure. Where am I?

I am the integral part of unlocking secrets. I'm the first half of how you type on a computer. Sometimes I'm chained so you don't lose me.

Both inside and out, you can never escape. I make up your bones, your eyes, and your face. When it gets cold, a phoney arrives. Use it gently when things go awry.
