Brought to you by the letter M.

Monday Morning. Metro. 

Monsieur, Miss. 

Muse, Marvels, Mouth

Mask, magic

Maybe more. 

Midday motel.

Mistress

Moist, mindless, mess

Madness. 

Money.

Moonlight, mood

Midnight murmur

Mere moment. 

Mislead, misread, 

Mistake

Music meets misery

Mundane, melancholy

Misplaced memory

Mute monster

Murder mystery.
