Blood Hunt is a 1995 crime novel by Ian Rankin, under the pseudonym "Jack Harvey". It is the third novel he wrote under this name. Gordon Reeve, a former SAS soldier, receives a phone call in his home in Scotland, informing him that his brother Jim has been found dead in a car in San Diego - the car being locked from the inside, and the gun still in Jim's hand. While in the USA to identify the body, Gordon realises that his brother was murdered, and that the police are more than reluctant to follow any lead. Retracing Jim's final hours, he connects Jim's death with his work as a journalist, investigating a multinational chemical corporation. Soon, Gordon finds himself under surveillance, and decides to find out more among Jim's acquaintances back in Europe. In London, he finds more hints, but no evidence for his brother's sources. After returning to his wife and son, he finds that his home has been bugged by professionals. Sending his wife and son to a relative, he determines to take on his enemy on his own. There are two parties after him: The multinational corporation, represented by "Jay", a renegade SAS member, and an international investigation corporation, somehow connected with the case.
