Saint Patrick's Day (Russian: День святого Патрика) is the second story-arc (and third book) in the Major Grom comic series. It ran for eight issues (#11–#18), and was written by Artyom Gabrelyanov and Ivan Skorokhodov and illustrated (mainly) by Alina Erofeeva and Anastasia Kim.
Having closed the high-profile Plague Doctor case, Igor Grom goes on a well-deserved vacation with his new girlfriend, Yulia Pchyolkina. The couple flies to Dublin, Ireland, where the national holiday St. Patrick's Day, is fast approaching—as is the British Royal Family's historical visit to the country. Shortly after Igor and Yulia arrive in Ireland, however, disaster strikes: Yulia vanishes from Dublin High Street, leaving behind only her shopping bags and a broken phone. In order to find her, Igor launches what might be the most dangerous investigation of his life, as he faces off against the largest criminal terrorist cell in Europe: St. Patrick's Children, a brutal and merciless holdover from the IRA.
Saint Patrick's Day provides examples of:
- Bad Boss: Murdock Macalister is verbally and physically abusive towards his underlings, treating them like incompetent morons.
- Bad People Abuse Animals: After Igor is captured, Macalister's Torture Technician, Billy, tries to break him by (among other things) stringing up a young bull in front of him and decapitating it with a chainsaw. There's even a close-up of the animal's eye filling with tears before it's killed. Igor responds by kicking the man in the throat with all of his strength.
- Subverted with Igor himself: after escaping from Billy, he uses a knife to...do something to another bullnote , causing it to bellow loudly and run away; in contrast to the previous scene, Igor only does so to cause a distraction, apologizes to the animal beforehand, and afterwards the bull is shown to be fine (though it does apparently die in the ensuing shootout).
- Bait-and-Switch: The first issue opens with a boarding call at a St. Petersburg airport; Igor tears frantically through the building, shoving past and jumping over passengers while he ruminates with deadly seriousness that he can't let a month's hard work go down the drain: that his struggles won't be in vain, and he will succeed. When he reaches his destination, it's revealed that he isn't pursuing a criminal, but racing to meet Yulia, so they can catch a flight to Ireland for their first vacation as a couple.
- Busman's Holiday: While in Ireland, Igor is supposed to be on a vacation from police work; he ends up spending the entire time attempting to solve the case of Yulia's kidnapping — and then taking down a wing of the IRA.
- Call-Back: In Issue #12, a newspaper in the police station has a front page story about Sergey Razumovsky's arrest. In Issue #14, Murdock researches Igor Grom on the internet, bringing up another article about the case (with the headline "Young Multimillionaire Accused of 200 Murders").
- One of the prostitutes in the Macalisters' brothel is Violet, Kirill Gretchkin's former favorite escort. Murdock's men trafficked her to Dublin.
- Dima Dubin is still taking care of Sergey Razumovsky's pet raven, Margo.
- Cold-Blooded Torture: The Saint Patrick's Children subject Igor to this after they take him prisoner.
- Crossover: Issue #14 reveals that Murdock Macalister is obtaining the group's weapons and ammunition personally from August Van der Holt (the Big Bad of Red Fury).
- Dysfunctional Family: As a family of terrorists, the Macalister clan are naturally extremely dysfunctional.
- Human Traffickers: Macalister's men operate (among other things) a sex trafficking operation, which they use to staff their brothel. Violet, the prostitute who previously appeared in Plague Doctor, is one of their victims, and they intend to do the same with Yulia.
- Oireland: Immediately upon setting foot in Dublin, Igor and Yulia are bedeviled by the red-haired, hot-headed, IRA-affiliated Macalister clan. When they aren't in the big city, they're in the windswept countryside.
- Rape Is a Special Kind of Evil: Macalister's goons are established as monsters by virtue of their sex trafficking operation. In their introductory scene, they attempt to rape the newly-kidnapped Yulia to "break her in".
- St. Patrick's Day Episode: The arc qualifies as one: Igor and Yulia's trip to Ireland coincides with the holiday (during which the British Royal Family is said to be visiting the country). The story even kicks off with Igor gifting Yulia a shamrock necklace on the plane to Dublin.
- Sex Slave: The St. Patrick's Children run a brothel filled with women who have been forced into sexual slavery. Among them is Violet, an escort who was last seen in St. Petersburg; she's clearly traumatized.
- Shout-Out: In Issue #11, Yulia responds to Igor's constant griping by comparing him to Grumpy Cat
.- In Issue #12, a newspaper article about Sergey Razumovsky's arrest features the headline "Genius Billionaire Philanthropist Serial Killer". In the same panel, Kirk O'Reilly is reading Aldous Huxley's Blind Man in Gaza.
- Dima has a Star Wars poster on his bedroom wall and a lamp shaped like Darth Vader's head.
- A flashback shows Chris sleeping with a Woody doll. He also has a Dude Cowboy movie poster on his wall.
- Tempting Fate: After Igor warns Yulia to "be careful" while shopping alone, she retorts, "What can possibly happen to me here? In the middle of Dublin?"
- You Wanna Get Sued?: In the first installment, Yulia goes shopping at what is clearly a Burberry store; the sign is angled so that the second "R" and the "Y" are off-panel.
- Western Terrorists: The Saint Patrick's Children are an Irish terrorist cell: a holdover from The Troubles.
