St Martin’s Day croissants

St Martin’s Day croissants are Polish crescent-shaped pastries whose poppyseed filling has an unintended consequence for Joanne Stuart: she fears it may register as heroin and morphine on a drugs test. Introduced by Agata as a festive specialty for the approaching November 11 observance, the pastries bring domestic pleasure into uneasy collision with the demands of Jo’s police work, then recur in her anxious account of a difficult night and a hurried return to her colleagues.

Appearance and Occasion

Agata presents the pastries after Jo has eaten her fill of a hearty meal, making their arrival a flourish at the end of an evening otherwise absorbed by food and conversation. They are exquisite crescents, iced and sprinkled with flaked almonds. Their celebratory presentation gives them the look of a carefully prepared seasonal treat, not a potential source of professional trouble.

Agata identifies them as St Martin’s Day croissants, also known as Marcinki, and explains that they traditionally come from a particular region and are eaten on St Martin’s Day, November 11, which also marks Polish Independence Day. With the date only a couple of weeks away, she has made them as practice. Their significance in the scene is therefore both cultural and personal: they bring Agata’s Polish food tradition into the shared meal, offered with evident pride and a desire to get the recipe right.

Ingredients and Refusal

When Jo asks what fills them, Agata lists poppyseed and almonds, corn syrup, sugar, and starch. The answer changes the mood. Jo’s face falls, and she clarifies that the problem is not an allergy: she is concerned about the poppyseed’s association with heroin. Agata laughs, treating the risk as familiar and harmless at the small quantities used in food sold in shops.

Jo’s objection is more specific than a general worry about eating poppyseed. She has been explicitly warned that it can register as heroin and morphine in a standard drugs test, and she cannot risk that result. She apologizes to Agata, who sits down and asks whether Jo is serious. Jo reaches across and squeezes her hand as she confirms that she is. The gesture keeps the refusal tender rather than dismissive: Jo declines the pastry because of a work-related constraint, while acknowledging the care behind Agata’s offering.

The Night and Its Aftermath

The croissants return to the narrative the following morning through Jo’s uncertainty about a night she cannot fully account for. She does not remember going to bed and cannot recall the details of her dreams, but remembers them as a succession of strange, frightening escapes. She attributes the experience to the plum brandy and the poppyseed and wonders whether she has experienced what being on heroin is like. This is her conjecture, not a confirmed effect of the pastry; the scene establishes her alarm and confusion, not a diagnosis or proof of intoxication.

Her phone then alerts her to a stream of messages, including one from Helen Gates and several from the same unrecognized number. A message timed at 9.02 asks where she is and says the others are waiting. Jo replies that she will arrive in fifteen minutes, but reaches them in about ten. As she drives, she worries that a speeding stop might have exposed her condition: her car’s alcohol self-test kit had put her on the amber-green boundary when she set off, while she has no way to know what her opiate level might be. She imagines the croissants would make a very poor explanation at a National Crime Agency disciplinary enquiry.

Nick Carter crosses the room to meet her and, seeing her appearance, expresses concern in blunt terms. Jo answers by repeating his judgment with the formal address Ma’am. The pastry episode thus ends not with a settled explanation of her dreams or test risk, but with Jo back among her colleagues, acutely aware that an ordinary festive food has become entangled with her professional credibility. Through that reversal, St Martin’s Day croissants connect a warmly offered cultural tradition to the bodily uncertainty, institutional scrutiny, and comic embarrassment of the morning after.
