Terrorism suspect Samantha Lewthwaite has written her followers a manual of war, also referred to by authorities as a “diary of death.”

Lewthwaite was the wife of suicide bomber Germaine Lindsay, a British native who fled the UK to execute terrorist acts.

In her diary, which has been transcribed by a disciple she recruited herself, she speaks about how radical Islamists should use the “element of surprise” to “get victory” against the Western enemy.

According to the Mirror, the mother of four is believed to be among the group heading and planning the attack on the Westgate mall in Nairobi, Kenya.

The document has been found in a safe house used by al-Shabaab terrorists in Mombasa, Kenya. The code is believed to have been used by the Somalian Muslim group.

“Treat others with dignity and respect as others do to us,” she writes.
