[Lynx-lynx]

Amazon AU has got a lot of Helen MacInnes' books at $1.99, not sure why or for how long, but they're all over $6 on Kobo AU.

These books are in the main thrillers, or espionage, and some are set in WWII, or the Cold War. They are stand alone books.

The Hidden Target
blurb:

Spoiler:

For Nina O'Connell, a trip round the world was the holiday of a lifetime. Travelling in a group, she is surprised when she runs into an old flame. But Bob Renwick is not there by chance.

He is on the hunt for two terrorists who have left a trail of murder in their wake, and soon Nina is caught up in a grim game of life or death,from Bombay to Washington's political elite.

Cloak of Darkness
blurb:

Spoiler:

Bob Renwick, founder of counter-terrorist agency Interintell, is handed a list of names, compiled by the ruthless executive of an international munitions firm, intent on removing anyone in his way.

To be on the list means death, and Renwick's name is third. On a desperate mission from New York to Djibouti, Renwick must unmask his nemesis to save all he holds dear.

Assignment in Brittany (This is my first MacInnes book and I've got only a couple of dozen pages to go - it's excellent imo!)
blurb:

Spoiler:

Three hours ago he had stood on English earth. Three hours ago he had been Martin Hearne... Now he was Bertrand Corlay. Martin Hearn had been summoned by Military Intelligence and given an important mission - enter Nazi-occupied France to gather information about German activities in the area.

But to do so Hearn must impersonate a Frenchman to whom he bears an uncanny resemblance, and that includes having to fool the women in Corlay's life.

When it becomes clear that Corlay was not simply an innocent French civilian, Hearn finds himself playing an increasingly dangerous game to outwit his Nazi enemies.

Above Suspicion
blurb:

Spoiler:

Richard and Frances Myles are preparing for their annual European summer vacation in 1939 when they are visited at their Oxford college by old friend Peter Galt, who has a seemingly simple job for them.

Galt asks if they would start their holiday in Paris, meet a man there, and then continue their journey as he directs.

But in the heightened atmosphere of pre-war Europe, nobody is above suspicion, in fact the husband and wife are being carefully monitored by shadowy figures.

Soon the couple are racing across Europe and must use all their ingenuity to stay one step ahead of the enemy.

Horizon
blurb:

Spoiler:

British soldier Peter Lennox, a POW in an Italian prison camp, is still fighting his own war. An artist in civilian life, his hands bear the scars of wounds received during his capture at the fall of Tobruk, and he suspects he will never paint again.

The only thing that sustains him is plotting his escapes, no matter how many times he is recaptured. But in September 1943 the Italians surrender to the Allies, and Lennox is free.

Wanting nothing more than to return to the fighting, he is instead assigned to the mountains of the South Tyrol as a liaison to a desperate band of resistance fighters.

With little more than courage and knowledge of the local terrain, Lennox and his comrades must help pave the way for an Allied push that may change the course of the war.

Neither Five nor Three
blurb:

Spoiler:

Paul Haydn was on his way home at last, to New York and the civilian life he longed for, after years of War.

Yet he would never forget the tormented people, desperate for refuge in Berlin. They had survived the War - but now a new, sinister presence threatened them, their families, the whole of society.

Now he discovered that, back home, some of his former colleagues had dangerous political sympathies, that someone was trying to discredit the woman he had once loved. The pattern seemed suddenly familiar.

He began to realise why there was such interest in his counter-propaganda skills.

Snare of the Hunter
blurb:

Spoiler:

Irina Kusak's recently divorced husband, Jiri Hr ádek, is a high-ranking official in the Czechoslovakian secret police: cruel, ambitious, utterly ruthless. So when he turns a blind eye to her defection to the west, she is uneasy.

Aided in her escape by a group of friends, including David Mennery, an American with whom she once had a passionate affair, Irina begins to feel herself truly free. But soon their journey becomes a nightmare.

It becomes clear that Hr ádek only allowed Irina to defect in order to bait a trap for her father, a world-famous author living in secrecy in the west, but when she refuses to lead Hr ádek to his quarry, Irina herself becomes his prime target.
As Hr ádek closes in and Irina's life hangs in the balance, David Mennery is drawn into a desperate fight to protect her and finds himself once more falling deeply in love...

Prelude to Terror (A Robert Renwick novel)
blurb:

Spoiler:

Art may soothe the soul and stimulate the mind but it doesn't save one's life from terrorists' bombs or bullets.” New York art expert Colin Grant takes on an easy commission: to travel to Vienna and bid on a priceless Old Master on behalf of a Texan millionaire.

The painting has been smuggled out of Hungary by a defector, and Grant must get it at any cost, while keeping his employer's name a secret. But all is not as it seems. No sooner has Grant landed in Austria than his seemingly simple assignment turns into a nightmare, as he finds himself at the centre of a conspiracy to unleash a wave of international terrorism.

Grant must now navigate a hidden and terrifying world, as he and the woman he loves become pawns in a war between the secret armies of East and West.

The Double Image
blurb:

Spoiler:

While carrying out research in Paris, American historian John Craig is surprised when he runs into his old college professor.

Sussman is a worried man. A survivor of Auschwitz, he is in shock, having seen and been seen by one of the Nazis who tortured him in the camp. But SS Colonel Berg has been dead for ten years - or has he?

Before Craig can help solve the riddle, Sussman is found dead and Craig is being questioned by the police. As various international organisations are drawn into the hunt for Sussman's killer, he realises that the ex-Nazi is far more than just a wanted war criminal.

Soon Craig's search for the truth takes him from Paris to the island of Mykonos, where he must unmask a dangerous and powerful foe.

Pray for a Brave Heart
blurb:

Spoiler:

It was 1953, and nothing could shake William Denning's resolve to leave the army and return to the States. Nothing, except one of the largest diamond hauls ever - which, in the wrong hands, on the wrong side of the Iron Curtain, was a potentially lethal force.

In a small village in the Swiss mountains, Denning discovered that there was not only a jewellery robbery at stake. In the ruthless world of espionage and international conspiracy his adversaries were the most unlikely people - and the most dangerous.

The Salzburg Connection
blurb:

Spoiler:

He demanded the immediate dispatch of two suitably trained operatives to Salzburg. Extreme measures might be necessary.

In 1945, with their thousand-year empire falling around them and the Allies on their heels, the Nazis hide a sealed chest in the dark, forbidding waters of the Finstersee - a lake surrounded by the brooding peaks of the Austrian Alps.

There it lies for twenty-one years, almost forgotten, until a British agent decides to raise it from the depths. The secrets he uncovers are far-reaching and lethal, and in Salzburg, Bill Mathison, a New York attorney on the trail of a missing colleague, finds himself drawn into the shadowy underworld of international espionage.

Not knowing who to trust amidst the chaos, he is drawn to two beautiful women, one of whom will betray him.

Ride a Pale Horse
blurb:

Spoiler:

When Karen Cornell, a beautiful journalist on assignment in Czechoslovakia, agrees to help a would-be defector by carrying top-secret documents to Washington, she is pulled into an astonishing web of terrorism, political assassination, blackmail, espionage, and treason in the highest levels of both superpowers.

One false move could cost Karen her life - and throw the world into a violent war.

Agent in place
blurb:

Spoiler:

Chuck Kelso is an idealist. When he steals a top-secret NATO memorandum, he only intends to leak it to the press; but it is soon in the hands of a Russian agent, a man who has spent nine years quietly working himself into the fabric of Washington society.

Within hours it has reached the KGB, and the CIA's top man in Moscow has had his cover blown. For British agent Tony Lawton, hunting down the Russian operative - the 'agent in place' - is a welcome challenge.

But for Chuck's brother, the journalist Tom Kelso, and his beautiful wife, Thea, the affair has unleashed a very special terror. Now the race is on to find the Russian spy before a top-level NATO conference. But why is the escaped agent behaving so strangely? Is he who he seems?
