Lewis McGregor Nordea Bank Finland PLC authentic looking check in the mail e. midland, Ontario Canada

letter in the mail today.  no return address on the envelope.  addressed to my husband.  my eyes got wide when i saw a very authentic looking check for 3,980.00.  i have done nothing with it other than look up the names on the check here.  i am to call lewis mcgregor 1-647-686-1596 in canada.  i looked up the area code and that is correct.  i looked up the bank it was drawn.  nordea bank finland plc of new york - real bank.  the company sending it came from a third place - century securities inc.  Gorham, Maine.  my husband and i decided it had to be a scam but what would happen if we cashed the check somewhere other than our bank?  it looks very real.  i am planning on following the rule of "you can not get something for nothing"
