Miss Matilda Hayward has a wedding to plan and while ordering her bridal bouquet in Bridal Lane, she finds a note in her sample bouquet requesting a liaison. Innocently believing the note to be a mix-up, Matilda engages her brother, Daniel, to attend the liaison with her, but the young paramour rushes off. He is later found beaten and bruised in an alley off Bridal Lane by Matilda's fiancé, Detective Thomas Ashdown, and his partner, Detective Harry Dart.
When a respected lacemaker is also found murdered in the same laneway, the note takes on a new significance. Matilda is assigned to write the obituary for the Women's Journal with her illustrator friend, Miss Georgina Urry, and soon finds herself embroiled in danger in the middle of a murder case, much to her fiancé's displeasure. There is mystery, danger, and love afoot before Matilda makes it to the altar!
