I understand why it’s tempting to use the word peak when describing an excited stage of interest in or curiosity about something. After all, a peak is the pointy top of something, so it’s natural to think of a peak when you think of your interest or curiosity swelling, but saying The story peaked my interest is wrong.
The correct word is pique, as in The story piqued my interest or My curiosity was piqued by his subtle innuendo.
Save the peaks for the mountain tops and lemon meringue pies.
