A Hopins Mystery -Tchaikovsky beware!

I peered into a Hopkins shop window that was decorated with a Christmas display. The ubiquitous antique nutcrackers exhibited their toothy growls. I instinctively felt myself protect my zipper fly. The military nutcrackers surrounded a little yellow book ominously - “The Mystery of the Toy Drummer”. On the cover two Patty Duke look alike detectives were examining a tiny Toy Drummer. Hmmmmm. What could this mystery be?
Had the family jewels had been stolen? Was his drum defective? Would they turn him upside down, and inside out, in their investigation?
The underlying theme was too painful. I rushed away, mystery unanswered. Tchaikovsky that!
