"Brick Fiend," by Joseph S. Walker, in Die Laughing: An Anthology of Humorous Mysteries, edited by Kerry Carter, Mystery Weekly Magazine, 2021.
I usually review stories in the year in which they are published, but I did not get my hands on this book (in which I have a story) until a few months ago.
This story, by the way, marks Walker's seventh appearance in this blog. It reminds me of a New Yorker casual, since it begins with (and was no doubt inspired by) clippings from two articles. They refer to a "massive LEGO theft ring," stealing sets of the popular toys to sell at a sizable markup.
The narrator is a brick fiend, shamefully addicted to LEGO games, "that sweet space where all that matters is the next brick and the rest of the world just gently detaches itself and drifts away."
When his pusher's supply dries up our hero gets desperate. Worse, he is being pursued by a cop: "Partner of mine stepped on a loose pile of two-by-two bricks one of you animals left laying around." Very funny stuff.
