DOGS of Lincoln Park (Storycuts) [EPUB ebook] 

Three young women — competitive, bitchy and moneyed — have lunch together at their favourite Korean restaurant every Friday. When the friendly chef from the restaurant moves into the same building as one of the girls, she strikes up a friendship with him. But the disappearance of her dog sparks suspicion of the Korean chef’s motives, and his culinary ambitions. Part of the Storycuts series, this short story was previously published in the collection If You Liked School, You’ll Love Work.
