When they next meet Saigō is a considerably more skilled martial artist than Linnear and defeats him quickly. Later we learn Saigō has joined a Kuji-kiri ryu in order to learn black ninjutsu

 and has become a ninja.

Linnear himself soon becomes introduced to Aka i ninjutsu, or the red, ostensibly "good" side of ninjutsu, through the Tenshin Shoden Katori Shinto Ryu.

The ninja are introduced not as magical or almost mythical people, but rather as supreme martial artists who have reached the highest level and seek to progress further. It is suggested that by becoming ninja they strive to advance to an even higher plane, gaining skills such as haragei, or sensing the surrounding world in a different manner. However, we soon learn this is not without a high personal cost.

). The local police are baffled and consult Nicholas as he is known to be an authority on oriental studies. Linnear quickly realises that a ninja is the murderer and the next target is his new girlfriend's father, Raphael Tomkin, whom he begins working for as a bodyguard, although not without persuasion. Linnear also befriends Lew Croaker, a local detective.

Linnear's investigations reveal Saigō is the ninja and this puts him on a deadly collision course with his older cousin.

Characters

Linnear and Saigō are portrayed as opposites. Linnear is a little cold, hero and Saigō is a violent and dangerous foe. Both are equally skilled in their disciplines, differing only in the philosophy that drives them. Both men are troubled. Saigō battles with his inner demon of self-doubt, often resorting to mind-expanding drugs, whilst Nicholas is a man torn between two worlds and feeling he belongs to neither.
