# Alexander Grierson — The Layton Court Mystery character guide > Alexander Grierson in The Layton Court Mystery by Anthony Berkeley. **Role:** major **Also known as:** Alec, Alexander Watson, Mr. Alexander Grierson, Mr. Grierson, Watson **First appearance:** 0001-the-layton-court-mystery ## Snapshot Roger's loyal, level-headed friend and reluctant accomplice, whose quiet caution keeps the amateur detective's wilder theories from doing real damage. ## Who they are Alec Grierson is a well-off young Oxford cricketer invited to Layton Court partly as a match for Barbara Shannon, and he brings Roger along as his friend. Where Roger leaps to conclusions, Alec hangs back — gently steering him off false trails and trying to stop him putting his foot in it with suspects. His steady presence matters because he is both the reader's sanity check and the emotional thread linking the house party to the outside world. ## Relationships ### [Roger Sheringham](https://www.betterreads.dev/discover/the_layton_court_mystery_se/characters/roger_sheringham) _friendship_ Alexander Grierson and Roger Sheringham are close friends and intellectual companions, often engaging in lively discussions and collaborative detective work. ### [Lady Stanworth](https://www.betterreads.dev/discover/the_layton_court_mystery_se/characters/lady_stanworth) _social_ Alexander Grierson and Lady Stanworth are cordial acquaintances, interacting primarily as fellow guests at Layton Court. ### [Major Jefferson](https://www.betterreads.dev/discover/the_layton_court_mystery_se/characters/major_jefferson) _rivalry_ Alexander Grierson and Major Jefferson have a tense, competitive dynamic, often disagreeing on matters of logic and honor. ### [Mrs. Plant](https://www.betterreads.dev/discover/the_layton_court_mystery_se/characters/mrs_plant) _friendship_ Alexander Grierson and Mrs. Plant share a friendly, cooperative rapport, with Mrs. Plant often assisting him with household details. ### [Barbara Shannon](https://www.betterreads.dev/discover/the_layton_court_mystery_se/characters/barbara_shannon) _friendship_ Alexander Grierson and Barbara Shannon are friendly and respectful companions, often discussing the case together. ### [John Prince](https://www.betterreads.dev/discover/the_layton_court_mystery_se/characters/john_prince) _friendship_ Alexander Grierson and John Prince are amiable acquaintances, often found in each other's company during social gatherings. ### [Roger Sheringham](https://www.betterreads.dev/discover/the_layton_court_mystery_se/characters/roger_sheringham) _friendship_ Alexander Grierson and Roger Sheringham are close friends and intellectual companions, often engaging in lively discussions and collaborative detective work. ### [Roger Sheringham](https://www.betterreads.dev/discover/the_layton_court_mystery_se/characters/roger_sheringham) _friendship_ Alexander Grierson and Roger Sheringham are close friends and intellectual companions, often engaging in lively discussions and collaborative detective work. ### [Lady Stanworth](https://www.betterreads.dev/discover/the_layton_court_mystery_se/characters/lady_stanworth) _social_ Alexander Grierson and Lady Stanworth are cordial acquaintances, interacting primarily as fellow guests at Layton Court. ### [Major Jefferson](https://www.betterreads.dev/discover/the_layton_court_mystery_se/characters/major_jefferson) _rivalry_ Alexander Grierson and Major Jefferson have a tense, competitive dynamic, often disagreeing on matters of logic and honor. ### [Mrs. Plant](https://www.betterreads.dev/discover/the_layton_court_mystery_se/characters/mrs_plant) _friendship_ Alexander Grierson and Mrs. Plant share a friendly, cooperative rapport, with Mrs. Plant often assisting him with household details. ### [John Prince](https://www.betterreads.dev/discover/the_layton_court_mystery_se/characters/john_prince) _friendship_ Alexander Grierson and John Prince are amiable acquaintances, often found in each other's company during social gatherings. ## In the story ### [The Layton Court Mystery](https://www.betterreads.dev/discover/the_layton_court_mystery_se/chapters/the-layton-court-mystery) Roger's friend and fellow guest, present at the house party. ### [I: Eight O’Clock in the Morning](https://www.betterreads.dev/discover/the_layton_court_mystery_se/chapters/i-eight-o-clock-in-the-morning) A large, broad-shouldered young man, newly engaged to Barbara Shannon;
