Callison is an author I didn't know, his writing style is closely resembling that of Alistair McLean, an author I loved. Peter Ross, the I in the book, could be one of McLean's leads.
I liked it, never read something about the salvage business. It was exciting and had an ending that I didn't expect. ( )

Peter Ross, Captain of the salvage tug, Tactician, currently in the Mediterranean Sea receives a plea for help from a freighter. As he approaches the ship, he sees it attempt to ram him then proceed to ground itself on rocks close to shore. He then sees the crew take to the lifeboats into a storm tossed sea where he sees boats overturn and the seamen drown before his eyes.

When he attempts to salvage the freighter from the rocks, he discovers some of the freighter's crew are still aboard and they seem to have a different agenda that appears to be they do not want the vessel saved. As some of his crew are killed and injured in suspicions accidents, he knows that there is some reason people do not want this ship saved. His challenge is to find out what before he loses his life and tug. ( )
