Given by: Garrus on the Normandy
Location: Normandy, MSV Fedele
Requirements: Spectre Status

1 - The One That Got Away
The third time you talk to Garrus on the ormandy, he will tell you a story from his C-Sec days. He had been after a rogue geneticist named Dr. Saleon who was performing unspeakable experiments on the poor residents of the Citadel. The doctor managed to escape and Garrus was never able to bring him to justice.

2 - The Mad Scientist
Head to the Herschel System in the Kepler Verge and locate the doctor's ship, the MSV Fedele. In a compartment towards the bow you will find Dr. Saleon himself. He maintains his innocence, claiming that he is "Dr. Heart," but Garrus will recognize him. Regardless, the doctor won't be taken alive and you will have to kill him. Return to the Normandy after you have looted all the nearby containers.
