The fourth series, Aloha, Hawaiian Dick, began publication through Image Comics on April 20, 2016, with artists Jacob Wyatt and Jason Armstrong handling the art on the lead and back-up stories, respectively.
Shortly after discovering this, Byrd, Mo, and Grimes are involved in a high-speed shoot-out in which the car gets riddled with bullets and they end up off the side of the Pali Highway.
Byrd and Mo discover that instead of drugs being stashed in the car's trunk, Bishop Masaki's lover, Leila Rose, was in there bound and gagged.
Moving as far as possible, Byrd and Mo just escape from the clutches of the Pali Highway Night marchers, the spirits of Hawaiian warriors, though Grimes is swept away in the tumult, screaming.
A shoot-out begins, during which time Auntie Chan gets shot, but stops when Bishop Masaki sees Leila Rose coming toward him during the storm.
It is only when a flash of lightning strikes too late that Masaki sees Leila for the corpse she has become before she embraces him and they fall off the pier and into the roiling ocean.
In The Last Resort, Byrd is hired by Italian mafioso, Red Piano, to investigate who is trying to stall and sabotage the opening of his casino-resort, the Seaside Sands.
He figures the trouble is being caused by his Irish rival, Danny Quinn, at the competing casino-resort, the Coral Reef.
Byrd, trying to figure a way out of the mess, is aided by what appears to be the spirit of Leila Rose who unties him and directs him toward a window to jump out of.
In the meanwhile, Mo is recognized by men of Quinn's who also kidnap the large detective and hold him until they can murder him and dispose of the corpse.
On his way, Mulligan hears strange noises in the wood and is waylaid by a Hawaiian spirit who runs him off a cliff and into the ocean below.
Quinn, in an uproar, storms into Piano's establishment and demands justice, though he is placated at first when they reveal that none of them killed Mulligan.
During this time, Quinn's men are also trying to kill Mo, who has escaped the speedboat they were taking him out into the ocean with, along with one of his captor's weapons.
Quinn, furious about the attack he perceived to come from Red Piano, and about the fact that the Irish mafia just severed ties with him (by telephone), takes his men over to the Seaside Sands to have it out with the Italians.
An alcoholic, Byrd often visits bars at or near the locations he is paid to investigate and he seemingly prefers nearly any sort of drink (though the ones he is most often illustrated with appear to be either straight whiskey or bourbon).
Byrd is also extremely reckless in his job as a detective, smart-mouthing almost everyone he meets, even to his detriment which may include beatings and attempts on his life.
The cases Byrd finds himself involved with also often include some element of the supernatural from native Hawaiian culture, though he remains in denial of what he truly knows.
At some point Leila Rose fell in with Bishop Masaki, and was eventually accidentally shot by Mo Kalama as she rode in the trunk of a stolen car.
Trained in a range of mysticism, Auntie Chan met her end on the Pali Highway when the Night Marchers came through.
In Hawaiian Dick, the Night Marchers are portrayed as spirits of vengeance, seeking their revenge toward those who fail to show the proper respect for their homeland.
The only survivor of the shoot-out between Red Piano and his men, and Danny Quinn and his, Anthony Antonio flees with Byrd and company back to Honolulu.
