In this mystery, tension climbs.
All the clues are hid in rhymes!

It's a holiday delight,
telling of a spooky night.

In that night, down darkened streets
two children go beg for treats.

"Halloween? We ignore dangers
and take candy gifts from strangers!"

Mark and his friend Ann did good,
visiting their neighborhood.

Candies soon would fill their sacks.
They should carry home their snacks.

Skies were dark, with moonlit clouds,
but they'd left the begging crowds.

for one last house, though they didn't know
it's one spot where they shouldn't go.
