Henry is a human trained as doctor and psychic, who belongs to the Sluagh. He can project his emotions.
Henry says that in his mortal days he could have been killed because he was a witch and has a the hump on his back, so he could be accused of dealing with devil. He had to leave human world once he was seen with some Sluagh. He became a member of Sluagh also because he was curious and wished to learn more about different races. He treated many of the lesser fey, e.g. he helped at births of brownies. Henry is also the one who successfully transplanted a nightflyer's tentacle on Mirabella.
He can't leave the faerie anymore, because he stayed there too long and should he leave it, all the years spend in faerie would catch up with him instantly.
When Meredith and Sholto enter Sluagh mound with wounded Mistral, Henry is fetched to tend to the wounded in Sholto's room. He also advises Meredith on drinking a cup of mulled wine, since he is afraid of her being in shock. He promises it won't harm her babies. He explains his theory that cold iron is poisonous to Sidhe because it negates magic, so Mistral needs his magic replaced.
When an entrance to a garden appears in Sholto's room, Henry stays behind in the room, he holds the door to the garden when Sholto and Meredith carry Doyle, whom they have taken from hospital, to the garden.
After Doyle and Mistal are healed, Henry warns all of them, that the doors from Sholto's room to the garden are disappearing. When everybody gets to safety of Sholto's room, Henry explains, that they have been inside the garden for days and the Sluagh has voted in a proxy king to deal with Seelie, who besieged the Sluagh mound and demanded the Sluagh to hand over Meredith.
