Those who remember World War I and the contemporary writing of that day, will recall Gerard's My Four Years in Germany as one of the outstanding books of history in the making. Now this retired diplomat reminisces of past experiences in a rich life. Following the years in Germany, he was sent as special representative to Mexico, to the Court of St. James during the coronation of George VI, and so on. The third generation of a family of fine lawyers, Mr. Gerard had an ""in"" with Gotham society a half century ago, attended the fabulous costume balls, visited Newport in its heyday. He writes too of the ""cloud cuckoo"" world of Germany before the war -- of hunting with a noble Hungarian in-law. There are accounts of more serious activities,- his political career campaigning for Teddy Roosevelt in the 1912 election; his career on the bench; a grizzly New York murder case. A book of largely nostalgic appeal to an older generation.
