- "I don't guess. I observe. And once I've observed, I deduce."
Sherlock Holmes is a consulting detective for the NYPD's 11th Precinct and Scotland Yard. Born on January 6, 1973 to May and Morland Holmes, he had a brother, Mycroft. He has a brilliant, deductive mind and instantly notices slight details that escape most people's attention. He has an incredible memory for items that assist in criminal investigations but is ignorant of common knowledge, such as pop culture, and can be uncaring and rude. An expert on many subjects including chemistry and self-defense (which he practices on Bob), he uses a network of "Irregulars" in his investigations. He is a beekeeper, plays the violin and has a pet tortoise, Clyde.
At the age of eight, he was sent to boarding school by his father, Morland Holmes, where he was often physically bullied for being different due to his intelligence. Sherlock met Captain Tommy Gregson while working for Scotland Yard. Although Sherlock mostly worked on homicides, and Gregson was there to observe the counter-terrorism bureau, their paths still crossed. Holmes was forced to end his relationship with Scotland Yard after excessive drug use due to believing that his lover Irene had been murdered. In 2011, he went into hiding and moved to New York City. After several months, his father discovered his drug problems and forced him into rehabilitation. He spent six months at Hemdale, rarely communicating with anyone. His father then hired Joan Watson to be his sober companion after he left rehab.

That evening, Buros kills another officer, Casey Hatem, and more fibers like the ones found at Flynn's murder scene are found. Holmes confronts Daren, who created a website using sayings Holmes uttered at support group meetings. Holmes threatens to reveal to Daren's wife that he is having an affair if he doesn't take the site down. Watson discovers Charlie Riggs supplied Alec with Oxy and introduced him to Buros. From his testimony, Holmes realizes Buros shot both Flynn and then Hatem in order for an inspector's funeral to be held in which the armory would be barely manned in order to rob it of its weapons. However, Buros successfully robs the armory. From one of Buros' weapons stashes that was seized, Watson deduces that Buros was hiding the guns in furniture which were then transported to Mexico. Holmes deduces that Buros was on a strict timetable for sending the weapons which points to use of a cargo ship bound for Veracruz. Buros is found by Bell and an ESU team and arrested. At a support group meeting, Holmes looks at the site Daren created which only says "I'm sorry."|

Mason finds Chris was in a park using city surveillance footage and facial recognition software. Chris is found dead in the woods and Holmes discovers a journal hidden under a rock. Holmes finds that Chris received a $150,000 payment from the same company as Marissa, Purgatorium. Dr. Hawes finds Chris' brain was destroyed and an unidentified chemical found in his system. Holmes believes that Chris was part of an illegal drug trial that Marissa was the nurse on.

|"Seed Money": At the scene of the death of an elderly couple, Watson speculates they committed suicide but Holmes leads her and Bell into the building's basement where a burned body is found. Checking the third floor, the body is found to be Clay Dubrovensky, who had a doctorate in botany and genetic engineering. Holmes says that Clay's burning death, necklacing, is a trademark of a Brazilan gang, SDS. The next morning after breaking into Watson's apartment, Holmes wakes Watson by making her a smoothie with a blender. From some Russian coins found at Clay's, he's been able to identify the neighborhood the grow house is in. Watson tells Holmes that she's folding her private detective business and will be working for insurance company Leda as an in-house investigator. Meeting Captain Gregson at the grow house, they are puzzled to discover most of the pot plants are dead. Holmes spots a valuable, one-of-a-kind orchid, the Wutai Pingtung, on a shelf and believes Clay may have been killed over it. Barbara Conway, a senior VP at AgriNext is questioned by Bell, Holmes and Watson at her company's office. Having found that she bought a cabinet that had the orchid on it, she denies knowing Clay. Told they believe she killed Clay when he didn't deliver the orchid, she insists it was thrown in for free, the seller was anonymous and gives them the second orchid. Conway provided two bags of plant food and as Watson opens one filled with ground coffee and dried fish, Holmes tells her that's the wrong one for orchids. After Conway reveals that AgriNext was negotiating for Clay's release from the SDS in order to grow pot for them, Watson reviews AgriNext memos that proves this. In order to stimulate thought, Holmes opens the plant food bag with coffee and fish and the strong odor fills the room. Holmes tells Watson that he's decided to make Kitty his new partner. Watson calls Holmes and informs him of Conway's confession while he indicates that he's about to tell Kitty about her promotion. However, a call from Gregson interrupts asking for Holmes alone to come to a crime scene. Gregson shows Holmes the body of Melanie Vilkas, who went missing days before. Many burn marks are on Vilkas' back which match those that Kitty's abductor inflicted on her. They realize that the abductor has left London and is in NYC.|

- "Being loved by you is a dangerous thing, Sherlock. Probably why I'm still alive. Men like us, we're not meant to make such connections."
- "But what we do, it's not a job. It's a calling. We were born to do this work."
- "No. We're much better than that. We're two people that love each other. We always have been."
- ―Holmes to Watson
Dealing with post-concussion syndrome, Holmes meets Michael Rowan at a support group meeting.

The pair's relationship began rather rocky as Watson was Holmes's sober companion, but Holmes soon began to develop a respect for her potential skills in observation and deduction. As their relationship continued, Joan's willingness to not be bullied by him, and to give as good as she got, as well as her respect for him, began to cause his feelings to grow to affection, and eventually to the point he admitted that he loved her. His brother Mycroft even made the observation that Sherlock loved her more than anything else. This reached the point where Holmes willingly gave up his work as a detective to spend time caring for Watson during her cancer treatments.
A running gag on the show, Holmes often wakes Watson in amusing ways. Occasionally, Watson returns the favor.
When Holmes interrupted several of her assassination plans in London, Moriarty at first considered killing him. Intrigued by his deductive abilities, which she compared to her own, she created the identity of Irene Adler and arranged for him to visit her. As Irene, she was an American in London who restored historic paintings, stealing some so that she could properly preserve them, which Holmes chose not to report her for. Moriarty's passion for art is one of the few characteristics she retained as Irene. She seduced Holmes so she could study him and finding he wasn't a threat to her other operations, she staged Irene's death (leaving a pool of her blood and a note signed "M", the modus operandi of her primary assassin Sebastian Moran), and resumed her business as Moriarty. Moriarty was unaware of Holmes' subsequent descent into drug addiction and showed genuine regret when she found out about it.
