The Devotion of Suspect X

By Keigo Higashino. Excellent suspense.

Yasuko Hanaoka is a divorced, single mother who thought she had finally escaped her abusive ex-husband Togashi.
When he shows up one day to extort money from her, threatening both her and her teenaged daughter Misato, the situation quickly escalates into violence and Togashi ends up dead on her apartment floor. Overhearing the commotion, Yasuko’s next door neighbor, middle-aged high school mathematics teacher Ishigami, offers his help, disposing not only of the body but plotting the cover-up step-by-step. When the body turns up and is identified, Detective Kusanagi draws the case and Yasuko comes under suspicion. Kusanagi is unable to find any obvious holes in Yasuko’s manufactured alibi and yet is still sure that there’s something wrong. Kusanagi brings in Dr. Manabu Yukawa, a physicist and college friend who frequently consults with the police. Yukawa, known to the police by the nickname Professor Galileo, went to college with Ishigami. After meeting up with him again, Yukawa is convinced that Ishigami had something to do with the murder. What ensues is a high level battle of wits, as Ishigami tries to protect Yasuko by outmaneuvering and outthinking Yukawa, who faces his most clever and determined opponent yet.

Sanctus

By Simon Toyne. Excellent, none stop action in short chapters.

A man throws himself to his death from the oldest inhabited place on the face of the earth, a mountainous citadel in the historic Turkish city of Ruin. This is no ordinary suicide but a symbolic act. And thanks to the media, it is witnessed by the entire world.
But few understand it.

For charity worker Kathryn Mann and a handful of others in the know, it is what they have been waiting for. The cowled and secretive fanatics that live in the Citadel suspect it could mean the end of everything they have built – and they will kill, torture and break every law to stop that.

For Liv Adamsen, New York crime reporter, it begins the next stage of a journey into the heart of her own identity.
And at that journey's end lies a discovery that will change evrything

The Gallows Curse

By Karen Maitland. Very good and a nice pay off at the end.

The thirteenth-century is just begun and King John has fallen out with the Pope, leaving babies to lie unbaptized in their cradles and corpses in unconsecrated ground. Across a fear-ravaged England, the people are dying in sin. In the village of Gastmere, this has shocking consequences for servant girl Elena. Unwittingly drawn into a macabre scheme to absolve dying Lord Gerard of his crimes, death and betrayal haunt her dreams like a curse. And when Elena is threatened with hanging for a murder she did not commit, it is certain that unnatural conspiracy lies behind these dark deeds. But where can she turn? For in every face lies wickedness and in every shadow lurks treachery
