Mind Flight by Stephen Goldin

Good

During fourteen years in the Terran Intelligence Agency, Alan Cheney has been an exemplary agent. An accomplished telepath, he has never disobeyed an order, never failed an assignment, never performed below a level of supreme competence.

Now, at thirty eight, his powers have become more acute than ever before. And because of this, because he is one of Earth's top telepathic agents, his beautiful boss is going to find a killer with an unreadable mind - and have Alain Cheney murdered.
