📝 Description: Catalyst: A Dark Descent Into Delirium

Ianic Mathieu delivers Catalyst, a tale of psychological unraveling following Dr. Novak. After the sudden passing of his mentor, he tricks the devoted secretary to take over the renowned clinic. His life changes when a coworker mails him a collection of audio recordings. Analyzing these tapes triggers a descent into paranoia and insanity. The story unfolds through various documents such as news clippings, sticky notes, harsh letters from peers, tape transcripts, and a personal journal titled Descent into Delirium. This diary reveals his twisted mind and disturbing drawings. The mixed format builds a terrifying atmosphere where logic fails. Fans of epistolary horror and mental thrillers will appreciate this style. Readers who like straight stories might find the disjointed layout difficult. It appeals to those who enjoy unreliable perspectives and questions about medical morality mixed with supernatural fear. It is not for people wanting neat endings or simple plots.
